Sub-pico second chirped optical pulses with Triki–Biswas equation by exp(− Φ(ξ))-expansion method and the first integral method

Abstract

This paper studies Triki–Biswas equation by using two strategic and efficient integration schemes to retrieve chirped sub-pico second pulses. These reveal dark and singular soliton solutions to the model. The existence criteria for these solitons are also a part of the result.
