Cascade compression induced by nonlinear barriers in propagation of optical solitons

Ultrashort nonautonomous similariton solutions and the cascade tunneling of interacting similaritons

“…The phenomenon of soliton tunneling, first predicted by Newell [25] over four decades ago, has been the subject of intense research in a wide range of nonlinear systems [26][27][28][29][30][31][32]. For completeness, we now highlight some key results in the tunneling literature.…”

Influence of generalized external potentials on nonlinear tunneling of nonautonomous solitons: Soliton management

“…Nonlinear tunneling of optical solitons through strong nonlinear organic thin films and polymeric waveguides has also been investigated in [29]. Cascade compression of optical soliton with exponential background through nonlinear tunneling has been discussed in [30]. Compression of optical similariton in graded index waveguide with exponential decay is investigated by Wang et al [31].…”

Nonlinear tunnelling of superposed Akhmediev breather in PT-symmetric inhomogeneous nonlinear couplers with gain and loss

“…In the following, we discuss nonlinear tunnelling effect of controllable behaviors of the superposed AB structure in Fig. 1 (b) in the distributed parameter system with a diffraction/dispersion barrier on an exponential background in which the diffraction/dispersion distributed function z ( ) β in the form [8][9][10][11] …”

“…Serkin et al studied the nonlinear tunnelling of optical solitons through strong nonlinear organic thin films and polymeric waveguides [5], and also discussed firstly nonautonomous soliton tunnelling effects governed by the nonlinear Schrödinger equation (NLSE) with variable coefficients [6]. Yang et al [8] investigated the compression of the optical pulse by nonlinear barrier (NB) and nonlinear well (NW). Wang et al [9] reported that soliton can tunnel through the barrier in a lossless manner in certain circumstances.…”
