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

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 non-linear Schrodinger's equation. Bright and singular soliton solutions are revealed with this algorithm. (C) 2018 Elsevier GmbH. All rights reserved.
