This work presents fabricated silica microstructured optical fiber with special equiangular spiral six-ray geometry, an outer diameter of 125 µm (that corresponds to conventional commercially available telecommunication optical fibers of ratified ITU-T recommendations), and induced chirality with twisting of 200 revolutions per minute (or e.g., under a drawing speed of 3 m per minute, 66 revolutions per 1 m). We discuss the fabrication of twisted microstructured optical fibers. Some results of tests, performed with pilot samples of designed and manufactured stellar chiral silica microstructured optical fiber, including basic transmission parameters, as well as measurements of near-field laser beam profile and spectral and pulse responses, are represented.

This work presents results of researhes of fabricated pilot sample of chiral few-mode optical fiber (FMF) with induced twisting of 10 and 66 revolutions per meter, core diameter 11 µm (that almost corresponds to standard singlemode optical fibers), typical “telecommuniction” cladding diameter 125 µm and improved height of step refractive index profile. Proposed few-mode optical fiber supports 4 guided modes over “C”-band. We considered design and selection of desired technological parameters, based on results of computations, performed by both rigorous and approximation methods. Spectral curves of dispersion parameters are reprented as well as results of experimental measurements near-field laser beam profile and spectral and pulse responces of laser-excited optical signals.

This paper discusses novel approaches to the numerical integration of the coupled nonlinear Schrödinger equations system for few-mode wave propagation. The wave propagation assumes the propagation of up to nine modes of light in an optical fiber. In this case, the light propagation is described by the non-linear coupled Schrödinger equation system, where propagation of each mode is described by own Schrödinger equation with other modes’ interactions. In this case, the coupled nonlinear Schrödinger equation system (CNSES) solving becomes increasingly complex, because each mode affects the propagation of other modes. The suggested solution is based on the direct numerical integration approach, which is based on a finite-difference integration scheme. The well-known explicit finite-difference integration scheme approach fails due to the non-stability of the computing scheme. Owing to this, here we use the combined explicit/implicit finite-difference integration scheme, which is based on the implicit Crank–Nicolson finite-difference scheme. It ensures the stability of the computing scheme. Moreover, this approach allows separating the whole equation system on the independent equation system for each wave mode at each integration step. Additionally, the algorithm of numerical solution refining at each step and the integration method with automatic integration step selection are used. The suggested approach has a higher performance (resolution)—up to three times or more in comparison with the split-step Fourier method—since there is no need to produce direct and inverse Fourier transforms at each integration step. The key advantage of the developed approach is the calculation of any number of modes propagated in the fiber.

The method for predicting the residual lifetime of a field aged optical cable with based on the test results of its samples taken from a cable line is considered. The test results of the proposed method are presented on the example of four samples of optical cables from cable lines installed in different years. According to the test results, the need to control the strength of the optical fibers of the cable line to predict the lifetime of the optical cable is confirmed.

This paper discusses approaches to the numerical integration of the coupled nonlinear Schrödinger equations system, different from the generally accepted approach based on the method of splitting according to physical processes. A combined explicit/implicit finite-difference integration scheme based on the implicit Crank–Nicolson finite-difference scheme is proposed and substantiated. It allows the integration of a nonlinear system of equations with a choice of nonlinear terms from the previous integration step. The main advantages of the proposed method are: its absolute stability through the use of an implicit finite-difference integration scheme and an integrated mechanism for refining the numerical solution at each step; integration with automatic step selection; performance gains (or resolutions) up to three or more orders of magnitude due to the fact that there is no need to produce direct and inverse Fourier transforms at each integration step, as is required in the method of splitting according to physical processes. An additional advantage of the proposed method is the ability to calculate the interaction with an arbitrary number of propagation modes in the fiber.

We present new type of silica graded index laser-optimized multimode optical fibers (LOMF) with extremely enlarged core diameter up to 100 μm and “typical” “telecommunication” cladding diameter 125 μm. This optical fiber was designed for harsh environment Gigabit onboard cable systems and industrial networks. It differs by special optimized graded refractive index profile, providing low differential mode delay (DMD) for selected guided modes. We present some results of tests, performed for manufactured pilot 520 m length of described LOMF 100/125, concerned with its geometry properties as well as key transmission parameters—attenuation and DMD map.

All-optical processor capable of processing optical bits has been a long-standing goal of photonics. In this paper, we report the results obtained by numerical simulations regarding the designing of an all-optical combinational circuit of an adder and subtractor circuits based on Si3N4 microring resonators. The designs of combinational circuit like adders and subtractor based on the use of all-optical basic logic gates are discussed while presenting the numerically simulated results. Extinction ratios of 5.2 dB, 3.5 dB and 2.7 dB are obtained for the half adder, full adder and half subtractor, respectively.

The design of an acousto-optic-fiber simplex communication channel based on a two-mode optical fiber is proposed. The model of this channel has been described and the simulation of data transmission over such channel has been executed. The simulation results are presented. As examples the dependencies of bit error rate from a cumulative differential mode delay in the fiber optic link. They showed that, for optimal reception, the accumulated differential mode delay should lie within 1.1–1.5 rad. Measures are proposed to ensure the required value of a differential mode delay at the receiver input.

This paper presents the results of modeling the propagation of a triplet of solitons controlled by dispersion on dense maps with local nonlinearity in optical fibers of a fiber-optic communication line with a length of up to 10,000 km. It is shown that the inclusion on the dispersion map between optical fibers with a dispersion of the opposite sign of a nonlinear element with an inverse phase characteristic makes it possible to increase the length of the fiber-optic line, which supports the propagation of a triplet of solitons more than 2 times, and the dynamic range of the fiber-optical communication line is more than on 3dBm.

The paper presents the simulation results for the long-haul two-mode fiber-optic link with managing of differential mode delay. Two compensation schemes were considered (by using mode crossing and by using delay lines). The options for using the inclusion of units for differential mode delay compensation in linear optical amplifiers in the case of compensation of chromatic dispersion only at the reception at the far end of the link and in the case of compensation of chromatic dispersion on linear optical amplifiers were considered. Also, the option of differential mode delay compensation on dense maps was considered when compensation units are set in closures of cable line on the amplifier section.

In the present work, we attempt to predict the lifetime of the cable, taking into account the random nature of the effects on the optical fiber during cable production. In the analysis, we considered only impacts during cable production and, accordingly, were limited to the prediction of cable lifetime after acceptance and delivery of the product at the manufacturer’s warehouse.

This work presents some results of earlier on performed optimization of refractive index profile for 42 μm core 16-LPmode optical fiber for next-generation optical networks. Here special profile form provides total differential mode delay (DMD) reducing over all the mode staff under desired enhanced mode effective area. We propose method for simulation of "real manufactured" few-mode optical fiber (FMF) core geometry, differing from desired optimized structure by core asymmetrical ellipticity and refractive index profile deviation, including local fluctuations. Some results of following analysis of considered optimized FMF with inserted geometry distortions, performed by earlier on developed modification of rigorous mixed finite-element method showed strong DMD degradation that requires additional higher-order mode management. Therefore this work also presents results of design of mode division multiplexer channel precision spatial positioning scheme at FMF core end that provides one of the potentiality solution of described DMD degradation problem concerned with "distorted" core geometry due to features of optical fiber manufacturing techniques.

This work presents results of absolute error estimation performed for non-reflective optical time domain reflectometer (OTDR) event localization during wavelet analysis of optical fiber link trace by continuous Haar wavelet transform. We considered fusion splices of standard singlemode optical fibers with different insertion loss values. Here OTDR indications varied over range 0.020…0.550 dB, while Haar wavelet scaling coefficients were selected from 150 up to 3000. Following comparison of measured and evaluated results allowed for proposition the basic criterion for non-reflective OTDR event localization by wavelet analysis. It is “the center” of this event, and it is characterized by strongly reduced absolute error. During the next step of research, we compared diagrams of event localization error distribution and detected generalized Haar wavelet scaling coefficients that provide mentioned absolute error no more 2 m, which are also presented in this work.

This article describes an approximate analytical solution for the LP01 and LP11 modes in a step-index optical fiber with Kerr nonlinearity provided that only two these modes propagate in the fiber. A well-known Gauss approximation method was used to obtain a system of characteristic equations and expressions for propagation constants of the above modes under the conditions considered. Using the obtained formulas, there were calculated the spectral dependences of the LP01 and LP11 modes propagation constants for the sample of a step optical fiber.

In this paper is presented the analytical formula for calculating the coupling coefficient between a modes of arbitrary radial and azimuthal orders on the joint of optical fibers when the joint has an angular mismatched. The solution is obtained by a known method of Gauss approximation. As an example, the present work shows the calculations results of dependencies of mode coupling coefficients from angular mismatch for some low order modes.

This work presents an alternative fast and simple method for the design of a graded refractive index profile of silica few-mode optical fibers (FMFs) with enlarged core diameter that extremely improves mode effective area, and low differential mode delay (DMD). We demonstrate some results of refractive index profile optimization for 16-LP-mode FMF with enlarged core diameter up to 42 μm and mode effective area more 130 μm2 under DMD reduction less 120 ps/km all over “C”-band and less 40 ps/km at λ = 1550 nm region. We also propose approach for simulation of the deviation of “real” optical fiber geometry from the optimized form and rigorous method for analysis of large core complicated optical fiber. Here, FMF core asymmetrical ellipticity together with the refractive index profile distortions were considered. They were set and simulated by data from reports of the real commercially available laser-optimized multimode optical fibers of TIA/ISO Cat. OM2+/OM3 refractive index profile measurements, performed by lab optical fiber analyzer kit. We present results of researches of considered FMF DMD spectral curve degradation due to described core geometry deviation from the optimized form. It was noticed, that unlike to only refractive index local fluctuations, FMF core non-circularity strongly distorts higher-order mode field distribution that affects to spectral mode delay curves and may lead to critical total DMD increasing.
