Modern telecommunication networks approach the capacity crunch, which is associated with the so-called nonlinear Shannon limit. So, the passage to fiber optic links with few-mode optical fibers is considered as an alternative solution of the described problem concerned with high nonlinearity of conventional commercial single-mode optical fibers. Presently, various designs of fewmode optical fibers have been known, with the recently published works presenting experimental results demonstrating their potentialities for long-haul fiber optic links. A lot of models of longhaul fiber optic links with few-mode optical fibers have been developed based on which features of a few-mode optical fiber transport network were numerically simulated. This work presents the results of simulation of a 6000-km long-haul fiber optic link with a two-mode optical fiber and 100-km-per-span Erbium doped fiber optic amplifiers system under 100 Gbps DP-DQPSK data transmission. We studied the use of particular linearly polarized modes and optical vortices for signal transmission. The computation results were compared with the simulation of the same fiber optic link with a single-mode optical fiber under the identical conditions.

“…It is worth to recall that for a silica‐based fiber, depending on the fiber length, the incident optical power and the electrical signal bandwidth, either dispersive or nonlinear effects may dominate along the fiber. In order to determine which effect is dominant, two parameters known as the dispersion length and the nonlinear length have been introduced . These parameters define the length scales over which dispersive or nonlinear effects become important for the signal progress along the fiber.…”

SUMMARYWe present a new approach for the performance analysis of hybrid fiber/wireless communication systems. This approach is based on a co‐simulation using two types of dedicated software: the first is used for RF/wireless systems whereas the second is devoted to optical communication systems. The proposed method enables simultaneous simulation of all elements of the radio‐over‐fiber link with accurate modeling. A low‐cost wireless local area network over a fiber distribution system is implemented in order to validate the results experimentally. Simulation results are in good agreement with experimental measurements in terms of EVM evolution for different link element configurations. Copyright © 2011 John Wiley & Sons, Ltd.

“…In fiber optics, nonlinear dynamics is the physical principle of fiber-based optical devices, optical information processing, photonic material design, and optical signal transmission, which has greatly promoted the development of fiber lasers, fiber amplifiers, fiber waveguides, and fiber-optic communications. [6][7][8][9][10] For a fully understanding of the nonlinear dynamics in optical fibers, the propagation dynamics of optical pulses through a fiber can be governed by a fundamental nonlinear PDE, i.e., nonlinear Schrödinger equation (NLSE), [11] which cannot be solved analytically when dispersion and nonlinearity coexist. To solve the NLSE, the split-step Fourier method (SSFM) and its modifications have been applied for studying various nonlinear effects in optical fibers, mainly due to its straightforward implementation and relative accuracy compared with other numerical methods.…”

A physics-informed neural network (PINN) that combines deep learning with physics is studied to solve the nonlinear Schrödinger equation for learning nonlinear dynamics in fiber optics. A systematic investigation and comprehensive verification on PINN for multiple physical effects in optical fibers is carried out, including dispersion, self-phase modulation, and higher-order nonlinear effects. Moreover, both the special case (soliton propagation) and general case (multipulse propagation) are investigated and realized with PINN. In existing studies, PINN is mainly effective for a single scenario. To overcome this problem, the physical parameters (i.e., pulse peak power and amplitudes of subpulses) are hereby embedded as additional input parameter controllers, which allow PINN to learn the physical constraints of different scenarios and perform good generalizability. Furthermore, PINN exhibits better performance than the data-driven neural network using much less data, and its computational complexity (in terms of number of multiplications) is much lower than that of the split-step Fourier method. The results show that PINN is not only an effective partial differential equation solver, but also a prospective technique to advance the scientific computing and automatic modeling in fiber optics.
