A symmetric model based on optically pumped quantum dot (QD) spin-polarized vertical cavity surface emitting lasers (spin-VCSELs) subject to mutual coupling is proposed. Compared with the conventional solitary model, more plentiful dynamical regimes associated with different dynamical regions are displayed visually by numerous bifurcation maps, and the detailed direct numerical simulations accurately reveal the dependence of dynamical behavior on external and internal parameters through introducing mutual coupling scheme. We then find that the roles played by the mutual coupling strength and delay time are remarkably significant in intensifying the regime of complex dynamical oscillation. Beyond that, the crucial effects of capture rate, gain parameter, linewidth enhancement factor and frequency detuning on determining the evolvement of dynamical behavior in the mutually coupled QD spin-VCSELs model are shown evidently in the plane of the optical pump intensity and polarization. Through a comprehensive investigation of the dynamical behavior dependent on key parameters, the dynamical mechanism expressed in the current model can be adjusted and even controlled well. Therefore, the involved efforts are enlightening and foresighted to promote a deeply research in the field of QD lasers-based expansion.

Micro-ring resonators (MRs) are widely used in optical networks-on-chips (ONoCs) as key device to select and redirect optical signals. However, MRs have the inherent property of being sensitive to environmental temperature. With the fluctuation of environmental temperature, its resonance wavelength drifts, which can introduce more loss and crosstalk noise to ONoCs and make the network performance decline sharply. Therefore, it is very important to analyze the influence of thermal effect in ONoCs to solve this problem. In this paper, the theoretical models of loss and crosstalk noise changing with temperature are established from device level to network level, respectively. And a series of network performances of mesh-based ONoCs caused by thermal effect are systematically modeled and analyzed employing formal methods. Finally, we conduct case studies for mesh-based ONoCs using optimized crossbar optical router and crux optical router to evaluate the proposed method. The simulation results show that the performance of mesh-based ONoCs declines with the increase of temperature, which severely limits the network scalability . The formal methods have high portability and scalability, which can provide a criterion for the performance analysis of thermal effect in ONoCs and provide technical support for future research work.

Slow light devices with buffering capability play a critical role in all-optical signal processing. In this paper, multiple slow light phenomena are implemented based on plasmon-induced transparency (PIT) in our device. The device mainly consists of dual tooth cavities coupled with stub resonators, respectively. Temporal coupled-mode theory model illustrates that the triple PIT phenomena can be achieved based on different formation mechanisms. The simulation results calculated by the finite-difference time-domain method reveal that significant slow light response occurs at two wavelength regions. In addition, the parameters of structure have an important influence on PIT response and slow light characteristics. Moreover, the separate manipulation of wavelength, transmission and group index at transparency peak can be achieved in different slow light channels by adjusting the structural parameters. This plasmonic device is of great significance for the design of optical networks on chips.

The photoelectric hybrid network has been proposed to achieve the ultrahigh bandwidth, lower delay, and less power consumption for chip multiprocessor (CMP) systems. However, a large number of optical elements used in optical networks-on-chip (ONoCs) generate high transmission loss which will influence network performance severely and increase power consumption. In this paper, the Dijkstra algorithm is adopted to realize adaptive routing with minimum transmission loss of link and reduce the output power of the link transmitter in mesh-based ONoCs. The numerical simulation results demonstrate that the transmission loss of a link in optimized power control based on the Dijkstra algorithm could be maximally reduced compared with traditional power control based on the dimensional routing algorithm. Additionally, it has a greater advantage in saving the average output power of optical transmitter compared to the adaptive power control in previous studies, while the network size expands. With the aid of simulation software OPNET, the network performance simulations in an optimized network revealed that the end-to-end (ETE) latency and throughput are not vastly reduced in regard to a traditional network. Hence, the optimized power control proposed in this paper can greatly reduce the power consumption of s network without having a big impact on network performance.

In this paper, the nonlinear dynamics of a novel model based on optically pumped spin-polarized vertical-cavity surface-emitting lasers (spin-VCSELs) with optical feedback is investigated numerically. Due to optical feedback being the external disturbance component, the complex nonlinear dynamical behaviors can be enhanced and the regions of different nonlinear dynamics in size can be extended with appropriate parameters of spin-VCSELs. According to the equations of the modified spin-flip model (SFM), the comparison of bifurcation diagrams is first presented for the clear presentation of different routes to chaos. Meanwhile, numerous bifurcation diagrams in color are illustrated to demonstrate the rich dynamical regimes intuitively, and the crucial effects of optical feedback strength, feedback delay, linewidth enhancement factor, and spin-flip relaxation rate on the region evolvement of complex dynamics of the proposed model are revealed to investigate the dependence of dynamical behaviors on external and internal parameters when the optical feedback scheme is introduced. These parameters play a remarkable role in enhancing the mechanism of complex dynamic oscillations. Furthermore, utilizing combination with time series, power spectra, and phase portraits, the various dynamical behaviors observed in the bifurcation diagram are simulated numerically. Correspondingly, the powerful measure 0–1 test is employed to distinguish between chaos and non-chaos.

Images as a common information carrier are widely disseminated and used at present, meanwhile, image security and privacy protection are also facing severe tests. To enhance the security of images, an asymmetric double color images cryptosystem introduced optical chaos technology is proposed based on compression sensing (CS) and double random phase encoding (DRPE). It is the first time that the combination of CS, DRPE and optical chaos technology is demonstrated to the best of our knowledge. By means of the optical chaos keys generated by a constructed optical chaos model, the two color images are first decomposed into their respective Red–Green–Blue (RGB) channels, CS based on discrete wavelet transform is then performed for the first encryption. Afterwards, the second encrypion of DRPE in fractional Fourier transform domain (FrFT) with optical chaos technology is also used, and the asymmetric encryption by carrying out equal modulus decomposition (EMD) with optical chaos keys further enhance the security finally. Simulation results and security analysis confirm that the cryptosystem owns multi-layer protection and adequate resistance to brute-force attack, statistical attack, differential attack, noise attack and chosen-plaintext attack, which is efficient and capable of guaranteeing the security of images and can provide an alternative solution for image security and privacy protection.

Optical networks-on-chips (ONoCs) is an effective and extensible on-chip communication technology, which has the characteristics of high bandwidth, low consumption, and low delay. In the design process of ONoCs, power loss is an important factor for limiting the scalability of ONoCs. Additionally, the optical signal-to-noise ratio (OSNR) is an index to measure the quality of ONoCs. Nowadays, the routing algorithm commonly used in ONoCs is the dimension-order routing algorithm, but the routing paths selected by the algorithm have high power loss and crosstalk noise. In this paper, we propose a 5×5 all-pass optical router model for two-dimensional (2-D) mesh-based ONoCs. Based on the general optical router model and the calculation models of power loss and crosstalk noise, a novel algorithm is proposed in ordder to select the routing paths with the minimum power loss. At the same time, it can ensure that the routing paths have the approximately optimal OSNR. Finally, we employ the Cygnus optical router to verify the proposed routing algorithm. The results show that the algorithm can effectively reduce the power loss and improve the OSNR in the case of network sizes of 5×5 and 6×6. With the increase of the optical network scale, the algorithm can perform better in reducing the power loss and raising the OSNR.

Insertion loss and crosstalk noise will influence network performance severely, especially in optical networks-on-chip (ONoCs) when wavelength division multiplexing (WDM) technology is employed. In this paper, an insertion loss and crosstalk analysis model for WDM-based torus ONoCs is proposed to evaluate the network performance. To demonstrate the feasibility of the proposed methods, numerical simulations of the WDM-based torus ONoCs with optimized crossbar and crux optical routers are presented, and the worst-case link and network scalability are also revealed. The numerical simulation results demonstrate that the scale of the WDM-based torus ONoCs with the crux optical router can reach 6 × 5 or 5 × 6 before the noise power exceeds the signal power, and the network scale is 5 × 4 in the worst case when the optimized crossbar router is employed. Additionally, the simulated results of OptiSystem reveal that WDM-based torus ONoCs have better signal transmission quality when using the crux optical router, which is consistent with previous numerical simulations. Furthermore, compared with the single-wavelength network, WDM-based ONoCs have a great performance improvement in end-to-end (ETE) delay and throughput according to the simulated results of OPNET. The proposed network analysis method provides a reliable theoretical basis and technical support for the design and performance optimization of ONoCs.

Recently, there has been growing interest in triboelectric nanogenerators (TENGs) that can effectively convert various forms of mechanical energy input into electrical energy. In the present study, a novel Teflon/vitamin B1 powder based triboelectric nanogenerator (TVB-TENG) is proposed. Paper is utilized as a supporting platform for triboelectrification between a commercial Teflon tape and vitamin B1 powder. The measured open-circuit voltage was approximately 340 V. The TVB-TENG can be applied as a humidity sensor and exhibits a linear and reversible response to the relative humidity of the environment. Moreover, the change in relative humidity is also indicated by the change in luminosity of a set of light-emitting diodes (LEDs) integrated in the TVB-TENG system. The TVB-TENG proposed in this study illustrates a cost-effective method for portable power supply and sensing devices.

Cloud servers are very suitable for sharing and storing image data and meanwhile it is confronted with many security and privacy problems. Optical chaos and hardware implementation of image encryption possess distinct superiorities in secret image sharing. Hence, combining advantages of ARM-embedded platform Exynos4412 model, together with VCSEL subject to positive optoelectronic feedback, a novel color image encryption and transmission system is experimentally realized and appraised. We investigate dynamic behaviors of VCSEL and obtain chaotic output. An ADC module is utilized for optical chaos data acquisition. The improved gravity model and double sine map are exploited to encrypt image, and encrypted image is securely shared by cloud services. The user can download encrypted image and decrypt it by hardware board. The experiment results reveal that the system has an excellent resistance to common attacks. Compared to numerical simulation, our hardware implementation for such a color image encryption and transmission system is formidable to actualize, but we successfully implemented and tested in real-world environment. By comparing experimental and simulation results, the consistent results are found. Therefore, in case of similar encryption effect, user's information privacy protection in actual industrial or commercial systems can be securely guaranteed on our hardware platform.

The optical networks-on-chip (ONoCs) are gradually becoming the most promising candidate in multiprocessor systems-on-chip (MPSoCs). To further improve the reliability of information transmission by realizing error detection in the optical communication systems on-chip, the optical channel coding technology can be exploited into the ONoCs. In this paper, a novel silicon micro-ring resonators (MRs)-based optical group counting check technology is presented. Based on the proposed optical group counting check generator and calibration circuit, an on-chip optical information transmission mechanism with error detection retransmission is proposed and analyzed. In addition, the availability of the proposed method is verified during a case study in torus-based ONoCs with wavelength division multiplexing (WDM) using Crux optical router. The simulation results show that the proposed method can effectively improve the communication reliability of the ONoCs, significantly reduce the bit error rate (BER), and increase the Q factor. For example, when the network size of the WDM-based torus ONoCs is 6 × 5, the BER and Q factor of this network using group counting method with retransmission mechanism are 4.33×10−10 and 6.10, which are respectively 3.916×10−7 lower and 1.22 higher than the traditional WDM-based torus ONoCs communication. It follows that this work can greatly improve the reliability of optical information transmission, and then achieve the scale expansion of WDM-based ONoCs.

In this paper, we investigate the physical layer security for an asymmetric dual-hop radio frequency-free space optical (RF-FSO) communication system, in which a source transmits information to a multi-aperture destination (D) through a best relay under the wiretapping of a multi-aperture eavesdropper (E). The best relay is selected by a partial relay selection scheme in terms of maximum instantaneous channel gain for the RF link. Moreover, equal gain combining scheme is also used to process the multiple copies of receiving signal at D and E. Assuming all the RF channels are subject to independent and identical distributed (i.i.d.) Nakagami-m fading and all the FSO channels are modeled by i.i.d. Gamma-Gamma process, the secrecy performance in terms of secrecy outage probability and the probability of strictly positive secrecy capacity are studied, and the accuracy of the analytical results is verified by Monte-Carlo simulations.

Optical Networks-on-Chip (ONoCs) have been proposed as the most promising solution for on-chip multi-core processors interconnection infrastructure due to its low latency, low power dissipation, and high bandwidth density. In ONoCs, the mesh topology is a typical structure that is regarded as the one of the most primary choice in ONoCs design due to its regular structure, simplicity, and divinable scalability in terms of network performance and budget. However, mesh structure has low connectivity and high insertion loss and crosstalk noise, which severely reduce the energy efficiency and signal reliability. In this paper, we first propose a novel double-layer ONoCs structure based on a partition of Virtual-Cluster in mesh, named VCmesh, which contains two candidate communication modes: inter-cluster communication and non-cluster communication. Furthermore, we design the length-optimized-routing-protocol (LORP) to select the preferred with smaller number of hops. The analyses and simulation results indicate that the performance of the VCmesh network is better than that of the typical mesh structure, especially in terms of end-to-end (ETE) latency and throughput. In physical layer performance, the VCmesh has a higher signal-to-noise-ratio (SNR), which improves the transmission quality of the optical signal. In addition, compared with the typical mesh-based ONoCs, the VCmesh-based ONoCs reduce the minimum required laser output power for 16 nodes, 25 nodes, and 36 nodes by 52.4%, 85.6%, and 94.6%, respectively.

In this paper, tunable plasmon-induced transparency (PIT) is achieved in a novel and compact plasmonic system which consists of dual hexagonal resonators with rotatable rectangular bar embedded in resonators and a metal-insulator-metal (MIM) waveguide. The proposed structure is numerically investigated by finite-difference time-domain (FDTD) method. The numerical simulation results reveal that by rotating the embedded bar to different angles, PIT can realize in different wavelengths. Tunability in transparency peak wavelength, transmission, and optical delay are also obtained when the angle of embedded bars are changed. In addition, the influences of other structural parameters on transmission and optical delay are analyzed in detail. This proposed structure may provide a novel manipulation for tunable PIT and potentially be applied in highly integrated optical storage and switch devices.

A novel plasmonic power splitter with variable transmissions and selectable channels is presented using hexagonal resonator with inserted silver ellipse. Rotating the silver ellipse to different angles will break the symmetry of structure and change the propagation path of surface plasmon polaritons (SPPs). The finite-difference time-domain (FDTD) simulation results reveal that the variable transmissions and selectable channels are achieved by rotating the inserted ellipse. Besides elliptical core, other components such as rectangular and triangular core are investigated in detail. It proves that the selection of channels and variable transmissions can be realized when the structural asymmetry is introduced into the hexagonal resonator by rotating the inserted asymmetric core. Furthermore, comparing the simulation results of three different structures, it is found that the power splitter with elliptical core has larger transmission when the output ports is selected and it is easier to adjust the transmission according to the requirements since its error range of rotation angle is larger than the others. Therefore, the power splitter with elliptical core is more suitable for realizing variable transmissions and selectable channels.

Optical chaos has great advantages in image encryption and optical message secure transmission, hence a novel image encryption and transmission system based on optical chaos is proposed. In this paper, we introduce optical chaos generated by the semiconductor laser in the encryption process. For increasing the chaotic complexity of slave lasers (SL1 and SL2), the master laser (ML) is subjected to the optical feedback and the external optical injection from the driven laser (DL). Then the SL1 and SL2 can generate the optical chaotic signal simultaneously, which can be used as chaotic carrier and the key for better security. The secret key and a new chaos sequence for the permutation can be structured by selecting randomly numbers from the optical chaos signal generated by the SL1 (or SL2). Furthermore, the result of color image encryption based on the Hilbert curve (HC) can be improved by introducing the optical chaos, after employing logistic chaotic map, the pixel positions and values of plain image are changed disorderly. The security analysis and simulation results can demonstrate the feasibility of proposed algorithms. Moreover, under the condition of chaos synchronization between the SL1 and SL2, the encrypted image can be modulated by using the chaos masking (CMS) technique and transmitted in 10 km single mode fiber (SMF) channel from the SL1 to SL2. The bit error rate (BER) can be for less than 4.22×10-20 and high quality factor (Q-factor) can be also for more than 9.

Cloud as a developing technology provides convenient services to sharing and usage of images resource, but brings a threat to images security and privacy authentication. Optical chaos possess distinct superiority for image secure sharing, therefore, based on two mutually coupled semiconductor lasers (MCSL1 and MC-SL2), we theoretically propose a color image encryption system for secure resource sharing and introduce a watermarking method for images privacy authentication in cloud. In our work, after achieving chaos synchronization under proper parameters, two MC-SLs are used to transmit encryption/decryption key space generated by chaotic signal of MC-SL1 and user's key. We carry out digital watermarking and encryption of a color image before secure resource sharing in cloud. On the other side of cloud, we make some tests for decryption of color image by received key space and watermark extraction. Meanwhile, we discuss security performance of color image encryption/decryption and key space transmission process, and analyze secure resource sharing of color image in cloud.

Crosstalk noise and insertion loss are important factors influencing the performance of optical networks-on-chip (ONoCs), especially in wavelength division multiplexing (WDM) based ONoCs. These factors lead to a high bit error rate (BER) of the communication system, thereby reducing the reliability of the communication in ONoCs. All-optical coding on chip is one of the important methods to solve this problem, so a high-reliability communication scheme that utilizes all-optical coding in ONoCs is implemented in this paper. The scheme mainly exploits the characteristics of linear block codes to implement the function of checking and correcting bit errors. As a core part of implementing this scheme, a micro-resonators (MRs)-based all-optical linear block codes encoder is designed to encode the information sequence before transmission. When the encoded data arrive at the receiving end, an error detection and correction (EDC) module can detect and correct the bit errors according to certain rules. In addition, for bit errors that exceed the error correction range, a retransmission mechanism (RT) is activated in communication system to denoise and retransmit the uncorrectable data group. In order to verify the validity of the proposed approach, a case study is conducted in mesh-based ONoCs with WDM. The simulation results manifest that the information transmission quality can be effectively optimized by applying the reliable communication scheme to the ONoCs. This approach reduces the BER and improves the optical signal-to-noise ratio (OSNR) of optical signals. Under the same condition that the scale of network reaches the maximum, the OSNR is increased by 9.8301 dB and the BER is reduced by 12.4499 dB compared with the traditional mesh-based ONoCs. Therefore, this work has a great impact on improving the reliability of communication systems.
