A new model of nonlinear propagation of optical solitons with an initial linear FM through optical fibers with strong birefringence and losses has been developed. The model allows to practically improve signal transmission without distortion in ultrahigh-speed fiber-optic communication systems. The model is based on coupled nonlinear Schrödinger equations. This model shows the existence of solitons with a linear boundary FM in the considered fibers.
Controlling a bright bright-dark soliton through a waveguide coupling.
Analytical and numerical solutions are proposed that describe the relationship between bright and dark spatial solitons in disconnected optical waveguides of a planar structure. Waveguides m. made of self-focusing and self-defocusing material.
One-dimensional spatial solitons in AIGaAs waveguides.
Experimental results are given. studies of the propagation of one-dimensional (1- D ) spatial solitons in long plenary AIGaAs waveguides. Three types of spatial solitons were observed: fundamental, Manakova, and spatial solitons.
Internal reflection of one-dimensional bright spatial solitons.
The results of a study of the reflection of one-dimensional spatial solitons on a nonlinear surface between linear and Kerr-type media are presented. Investigated by physical. the conditions under which a beam reflected from a nonlinear surface remains a spatial soliton. The critical angles of incidence of the beam on the interface between the media and the dependence of the intensity of the reflected solitons on the angle of incidence are determined.
