Resonant optical soliton perturbation with full nonlinearity and time-dependent coefficients by trial equation method

Abstract

Optical soliton solutions are retrieved for the perturbed resonant nonlinear Schrodinger's equation with time-dependent coefficients, where perturbation terms appear with full nonlinearity. The trial equation method is the integration methodology adopted in this paper. There are five forms of non-Kerr law nonlinearity considered. Bright, dark and singular solitons are reported, that come with constraint conditions for the existence of solitons.
