In this work, a novel all-dielectric metasurface made of arrayed circular slots etched in a silicon layer is proposed and theoretically investigated. The structure is designed to support both Mie-type multipolar resonances and symmetry-protected bound states in the continuum (BIC). Specifically, the metasurface consists of interrupted circular slots, following the paradigm of complementary split-ring resonators. This configuration allows both silicon-on-glass and free-standing metasurfaces and the arc length of the split-rings provides an extra tuning parameter. The nature of both BIC and non-BIC resonances supported by the metasurface is investigated by employing the Cartesian multipole decomposition technique. Thanks to the non-radiating nature of the quasi-BIC resonance, extremely high Q-factor responses are calculated, both by fitting the simulated transmittance spectra to an extended Fano model and by an eigenfrequency analysis. Furthermore, the effect of optical losses in silicon on quenching the achievable Q-factor values is discussed. The metasurface features a simple bulk geometry and sub-wavelength dimensions. This novel device, its high Q-factors, and strong energy confinement open new avenues of research on light-matter interactions in view of new applications in non-linear devices, biological sensors, and optical communications.

The recent development of sophisticated techniques capable of detecting extremely low concentrations of circulating tumor biomarkers in accessible body fluids, such as blood or urine, could contribute to a paradigm shift in cancer diagnosis and treatment. By applying such techniques, clinicians can carry out liquid biopsies, providing information on tumor presence, evolution, and response to therapy. The implementation of biosensing platforms for liquid biopsies is particularly complex because this application domain demands high selectivity/specificity and challenging limit‐of‐detection (LoD) values. The interest in photonics as an enabling technology for liquid biopsies is growing owing to the well‐known advantages of photonic biosensors over competing technologies in terms of compactness, immunity to external disturbance, and ultrahigh spatial resolution. Some encouraging experimental results in the field of photonic devices and systems for liquid biopsy have already been achieved by using fluorescent labels and label‐free techniques and by exploiting super‐resolution microscopy, surface plasmon resonance, surface‐enhanced Raman scattering, and whispering gallery mode resonators. The current state‐of‐the‐art is critically reviewed here, starting from the requirements imposed by the detection of the most common circulating biomarkers. Open research challenges are considered together with competing technologies, and the most promising paths of improvement are discussed for future applications.

TM-pass polarizers are pivotal components of photonic integrated circuits (PICs), especially those intended for biosensing applications. In the literature, several silicon TM-pass polarizers have been proposed, designed and experimentally demonstrated, but their insertion loss is not compatible with the current trend of silicon photonics aimed at exponentially increasing the component density within PICs. Herein, we propose and design a TM-pass polarizer whose insertion loss is carefully minimized to 0.05 dB at wavelength 1.55 μm by utilizing a combination of an asymmetric directional coupler and a mode evolution section. The adoption of appropriate technical solutions makes this record insertion loss value compatible with a high extinction ratio equal to 38 dB close to 40 dB. With a device footprint of only 2.5 × 20 μ ${m^{2}}$ , the design exhibits an insertion loss less than 1.7 dB and extinction ratio better than 30 dB over a large bandwidth of 200 nm. The design assumes the constraints of a typical silicon photonics open-access technological process and a standard 220 nm silicon-on-insulator (SOI) wafer. A very low sensitivity of the achieved performance to reasonable fabrication inaccuracies is demonstrated, with a worst-case insertion loss of only 0.32 dB at wavelength 1.55 μm.

A comprehensive electromagnetic mathematical model of an ultra-high Q-factor 1D-PhC ring resonator (1D-PhCRR) is proposed. The 1D-PhCRR results by the integration of a 1D-PhC in a ring cavity and its operation is based on the slow-light effect, allowing an improvement of the Q-factor of at least three orders of magnitude in comparison with the values obtained for a ring resonator without the grating. Accurate modelling and simulation of such ultra-high-Q ring resonator require very long simulation time and huge computing resource by using the conventional numerical methods, as Finite Element Method (FEM) and Finite Difference Time Domain (FDTD), because of the structure complexity. Therefore, to overcome these bottlenecks, an accurate mathematical model has been developed, able to take into account the waveguide curvature and dispersion, and the effect of the grating in the coupling region, reducing also the computation time. An ultra-high Q-factor (> 109) 1D-PhCRR in Si3N4 technology with a footprint of 16 mm2 has been simulated in relatively short computer time, using the model described in the paper. This performance makes the 1D-PhCRR suitable for several applications, such as filters, ultra-sensitive biosensors and integrated photonic-gyroscopes, for which ultra-high Q-factor sensitive element ensures a high resolution.

Photonic ring resonators can be considered building blocks of new concept satellite payloads for implementing several functions, such as filtering and sensing. In particular, the use of a high Q-factor ring resonator as sensing element into a Resonant Micro Optic Gyroscope (RMOG), provides a remarkable improvement of the performance with respect to the competitive technologies. To qualify a ring resonator for Space applications, the radiation effects on it in the Space must be carefully evaluated. Here, we investigate the effects of gamma radiation on a high Q InGaAsP/InP ring resonator, for the first time, to our knowledge. The ring resonator under study has a footprint of about 530 mm2 and it is based on a InGaAsP/InP rib waveguide, with a width of 2 µm and a thickness of 0.3 µm, formed on a 0.7 µm thick slab layer on an InP substrate 625 µm thick. For a total dose of about 320 krad Co60 gamma irradiation, a mean variation of about 13% and 4% was measured for Q and extinction ratio (ER), respectively, with respect to the values before irradiation (Q = 1.36 × 106, ER = 6.24 dB). Furthermore, the resonance peak red-shifts with a linear behaviour was observed increasing the total dose of the absorbed radiation, with a maximum resonance detuning of about 810 pm. These non-significant effects of a quite high gamma radiation dose confirm the potential of high-Q InP-based ring resonators into Space systems or subsystems.

Antimicrobial resistance (AMR) describes the ability of bacteria to become immune to antimicrobial treatments. Current testing for AMR is based on culturing methods that are very slow because they assess the average response of billions of bacteria. In principle, if tests were available that could assess the response of individual bacteria, they could be much faster. Here, we propose an electro-photonic approach for the analysis and the monitoring of susceptibility at the single-bacterium level. Our method employs optical tweezers based on photonic crystal cavities for the trapping of individual bacteria. While the bacteria are trapped, antibiotics can be added to the medium and the corresponding changes in the optical properties and motility of the bacteria be monitored via changes of the resonance wavelength and transmission. Furthermore, the proposed assay is able to monitor the impedance of the medium surrounding the bacterium, which allows us to record changes in metabolic rate in response to the antibiotic challenge. For example, our simulations predict a variation in measurable electrical current of up to 40% between dead and live bacteria. The proposed platform is the first, to our knowledge, that allows the parallel study of both the optical and the electrical response of individual bacteria to antibiotic challenge. Our platform opens up new lines of enquiry for monitoring the response of bacteria and it could lead the way towards the dissemination of a new generation of antibiogram study, which is relevant for the development of a point-of-care AMR diagnostics.

Monitoring of bacteria metabolism/viability at single level during the antibiotics action is a crucial functionality for systems supporting the development of new drugs able to kill bacteria resistant to all or nearly all antibiotics currently available. In this paper, we report on an electro-photonic chip-scale microsystem including an array of photonic nanocavities each able to trap a single bacterium. By monitoring the spectral response of the nanophotonic cavities and the electrical impedance across the trapping sites, a detailed knowledge of the metabolic state of trapped bacteria can be obtained. By three-dimensional simulations based on the finite element method, we predict a high electrical detection resolution of the microsystem, with a current variation of a factor 12 between dead and live bacteria.

The study critically reviews the silicon-based microphotonic biosensors for biomedical applications. In particular, integrated optical devices and their advantages, in terms of high performance and compactness, and also high reliability and long life term, are reported. These features, together with the complementary metal oxide semiconductor compatibility of the silicon technology, since the last few years, have been allowing to realise high-efficiency biosensing platforms with on-chip integration of several biosensors for a multi-analyte detection. Many lab-on-chip systems integrated into portable medical instruments have been proposed in the literature and some of them already commercialised in the worldwide market, so attaining extraordinary improvements in the early detection and monitoring of several diseases. Therefore, fast and accurate self-tests achievable with silicon photonic biosensors are remarkably opening new possibilities and applications in the healthcare industry.

A multi-analyte biosensing platform for the selective label-free detection of protein biomarkers has been designed through a three-dimensional model based on the finite element method. The sensing element of the platform is a planar plasmonic nanocavity, consisting of a one-dimensional periodic structure (Bragg grating) in gold, with a defect, placed on the buried oxide of a silicon-on-insulator substrate. The footprint of this sensing element, which has a good chemical stability, is only 1.57 μm2. The sensor has a detection limit of 128 pg/mm2 and a surface sensitivity of 1.8 nm/nm.

A hybrid titanium dioxide/silicon rich nitride ring resonator with the unique feature of being simultaneously athermal and polarization-insensitive is reported for the first time to our knowledge. Although its potential application domain is extremely wide, the designed integrated microphotonic cavity, having a racetrack shape, is intended for notch filtering in a microwave photonic pass-band filter. A careful selection of the CMOS-compatible material system and an innovative design approach have allowed a very low dependence of the filtering shape on the input beam polarization and, simultaneously, a thermal drift of the resonance wavelength < 1.5 pm/K. The numerically estimated Q-factor, free spectral range, and extinction ratio are compliant with the requirements of the selected application, being equal to 7.8×104, 4 nm, and 30.7 dB, respectively.

Photonic integrated circuits technology now enables the integration of several hundreds of optoelectronic and photonic active and passive devices on a single chip. This technology is having a disruptive impact on the field of microwave photonics with the demonstration of chip-scale complex sub-systems for generating and processing RF signals. Such integrated microwave photonic circuits exhibit features very attractive in the field of space engineering such as small size, weight, and power consumption. In this paper, the space applications of integrated microwave photonics are discussed with a special emphasis on RF pass-band filters for reconfigurable telecom payloads and delay lines for wideband beamforming.

Several emerging application domains such as Internet of Things (IoT) and wearable electronic microsystems demand flexible solar cells that exhibit simultaneously low cost and high efficiency. Recent advances in the field of graphene-based solar cells have allowed the demonstration of cells with these features. In particular, graphene/silicon Schottky junction solar cells have demonstrated a very interesting performance in this context. The paper, after a review of the graphene-based solar cells, reports on some numerical results on a graphene-on-silicon flexible solar cell having an efficiency > 10% and two important advantages, the environmental stability and the low complexity of the fabrication process. The design of this solar cell has been carried out through a general and accurate mathematical model, which has been validated by using experimental data reported in literature.

Beam steering in phased array antennas for some demanding terrestrial and space applications needs ultra-wide band true-time tunable delay lines preventing the beam squint phenomenon. Recent advances in the field of integrated microphotonics have allowed the demonstration of compact chip-scale delay lines with fast and low-power tuning mechanisms. For the tuning, several approaches have been theoretically and experimentally investigated and among them, very promising results have been obtained by using graphene in resonant delay lines based on the slow light effect. In this paper, after a brief review on resonant microphotonic tunable delay lines, some selected recent results on an ultra-compact graphene-based optical delay line including a silicon Bragg grating, are proposed.

The design of a continuously tunable optical delay line based on a compact graphene-based silicon Bragg grating is reported. High performance, in terms of electro-optical switching time (tswitch < 8 ns), delay range (Δτ = 200 ps), and figure of merit FOM = Δτ/A = 1.54x105 ps/mm2, has been achieved with an ultra-compact device footprint (A ~1.3 x 10−3 mm2), so improving the state-of-the-art of integrated optical delay lines. A continuous and complete tunability of the delay time can be achieved with a very low delay loss ( = 0.03 dB/ps) and a weak power consumption ( = 0.05 mW/ps). A flat bandwidth B = 1.19 GHz has been calculated by exploiting the slow-light effect in the device. This performance makes the proposed optical delay line suitable for several applications in Microwave Photonics (MWP), such as beamsteering/beamforming, for which large delay range, flat and wide bandwidth and small volume are required.
