Sub pico-second pulses in mono-mode optical fibers with Kaup-Newell equation by a couple of integration schemes

摘要

This paper examines soliton dynamics of sub pico-second pulses modeled by Kaup-Newell equation. The modified simple equation scheme and trial equation approach retrieves dark, bright as well as singular solitons to the model. The constraint relations guarantee the existence of such solitons.
