Optical solitons to Schrödinger–Hirota equation in DWDM system with modified simple equation integration architecture

Abstract

Optical solitons called bright soliton, dark soliton together with singular soliton solutions were emerged in this work. Dense wavelength division multiplexed (DWDM) system corresponding to the perturbed Schrödinger–Hirota equation including spatio-temporal dispersion additionally group-velocity dispersion for kerr law nonlinear effect was analyzed through the medium of modified simple equation integration approach. Besides these optical soliton solutions, supplement solutions referred to as singular periodic solutions were formed.
