Evolution of circularly polarized pulse through a nonlinear chiral fiber

Abstract

Using Maxwell's curl equations and Post's constitutive relations, we obtained a generalized chiral nonlinear Schrodinger equation. This equation governs light transmission through a dispersive chiral fiber with combined action of chirality, nonlinearity, and dispersions. Simulations are based on the split-step Fourier beam propagation method and numerical results reveal the separate roles of dispersion and nonlinearity playing in the pulse evolution. For weak chirality, there is a possibility to modulate optical attenuation and nonlinearity which provides an additional dimension to balance the effects of dispersion and nonlinearity. These combined effects with the cooperation of chirality make temporal optical solitons for a single component which has an application in chiral fiber optic communications.
