Optical nonlinearity in 2D materials excited by spatial Gaussian laser beam is a novel and peculiar optical phenomenon, which exhibits many novel and interesting applications in optical nonlinear devices. Passive photonic devices, such as optical switches, optical logical gates, photonic diodes, and optical modulators, are the key compositions in the future all‐optical signal‐processing technologies. Passive photonic devices using 2D materials to achieve the device functionality have attracted widespread concern in the past decade. In this Review, an overview of the spatial self‐phase modulation (SSPM) in 2D materials is summarized, including the operating mechanism, optical parameter measurement, and tuning for 2D materials, and applications in photonic devices. Moreover, some current challenges are also proposed to solve, and some possible applications of SSPM method are predicted for the future. Therefore, it is anticipated that this summary can contribute to the application of 2D material‐based spatial effect in all‐optical signal‐processing technologies.

“…Physical phenomena, occurring at such interaction, are the basis for optoelectronic technologies and all‐optical technologies, for example. One of these phenomena is optical bistability (OB), 1‐17 which consists of the existence of two values for intensity of the pulse, transmitted through a medium, under the action of an incident optical pulse with a certain intensity. Thus, two stable states (an upper state and a low one) for the semiconductor characteristics are observed, and switching between the states could be realized at different intensities of the pulse.…”

The article is devoted to an effective numerical method for solving the 3D problem of laser‐induced plasma evolution in a semiconductor. The physical processes under consideration are accompanied by the existence of the nonlinear feedback between semiconductor characteristics. Mathematically the problem is described by the set of time‐dependent nonlinear PDEs, which involves the Poisson equation with Neumann boundary conditions. One of the problem complexities correlates with providing of well‐known solvability condition for the Neumann problem at its numerical solution. This condition for the problem under consideration coincides with the fulfillment of the charge conservation law, and it is necessary to take into account at developing the numerical method. We apply and compare two numerical approaches: the direct method and the iteration method for a numerical solution of the Poisson equation together with the solution of other PDEs. The computer simulation results are shown that using the direct method leads to the solution distortion because of the presence of the problem nonlinear feedback between functions containing in the equations, and this feedback leads to the conservation law violation. Opposite, using the iteration method for the Poisson equation solution allows us to fulfill the conservation law of the equations set, whose numerical solution is based on developed iteration process.

“…The optical properties of graphene have attracted a large number of attentions from researchers since its first mechanical exfoliation in 2004, in particular for Surface Plasmon-Polaritons (SPPs), which are evanescent electromagnetic waves coupled with free electron plasma oscillations [1]. SPPs can propagate on the surface of metal or graphene [2][3][4]. The wavelength of SPPs on metal is in the visible spectrum, while the wavelength of SPPs on graphene is in the near-infrared spectrum [5].…”

In this paper, we utilize coupled mode theory (CMT) to model the coupling between surface plasmon-polaritons (SPPs) between multiple graphene sheets. By using the Stimulated Raman Adiabatic Passage (STIRAP) Quantum Control Technique, we propose a novel directional coupler based on SPPs evolution in three layers of graphene sheets in some curved configuration.Our calculated results show that the SPPs can be transferred efficiently from the input graphene sheet to the output graphene sheet, and the coupling is also robust that it is not sensitive to the length of the device configuration's parameters and excited SPPs wavelength.
