Bright, dark and singular optical solitons to Kundu-Eckhaus equation having four-wave mixing in the context of birefringent fibers by using of modified simple equation methodology

The current paper studies pretty important optical solitons namely bright, dark as well as singular solitons in birefringent fibers having four-wave mixing through the governing model known as Kundu-Eckhaus equation which is coupled system and is modeled for soliton transmission along birefringent fibers. In order to get such solitons, the modified simple equation algorithm is employed. Also, singular-periodic solutions in addition to optical solitons are revealed by reversed restriction circumstances.
