Polarized Spatial Soliton in a Chiral Optical Fiber

Abstract

The problem of soliton propagation in nonlinearity Kerr medium with linear optical activity and cubic anisotropy is considered. It is shown that the balance between the nonlinearity and linear girotropic results in the existence of spatial polarized solitons with fixed states of polarization. The chirality effect is characterized through the Born-Fedorov formalism and the results show modifications of the attenuation and nonlinear coefficient compared with the tipical coefficients in a nonlinear Schrödinger equation for a normal fiber in a regime of 1.55 and 1.3 μm.
