Sub-pico-second chirped optical solitons in mono-mode fibers with Kaup–Newell equation by extended trial function method

Abstract

This paper employs extended trial function method to retrieve sub-pico-second optical soliton solutions to Kaup–Newell's equation that is one of the forms of derivative nonlinear Schrödinger's equation. Bright and singular soliton solutions are revealed with this algorithm.
