Abstract
•Optical solitons and other solutions in fiber Bragg gratings having dispersive reflectivity with parabolic form of nonlinearity are recovered in this paper.•The new Jacobi elliptic functions expansion has been utilized.•Chirped as well as chirp-free pulses are recovered.
This paper enumerates optical solitons and other solutions in fiber Bragg gratings having dispersive reflectivity with parabolic form of nonlinearity. The new Jacobi elliptic functions expansion has been utilized to achieve this goal. Chirped as well as chirp-free pulses are recovered.
