Optical solitons in Bragg gratings fibers for the nonlinear (2+1)-dimensional Kundu–Mukherjee–Naskar equation using two integration schemes

The current work handles for the first time, dispersive optical solitons in fiber Bragg gratings nonlinear (2+1)-dimensional Kundu–Mukherjee–Naskar equation. Two integration schemes, namely, modified Kudryashov’s approach and addendum to methodology are applied. Dark bright soliton solutions as long explicit obtained. Also, combo bright-singular introduced.
