Pt-Symmetric Nonlinear Directional Fiber Couplers with Gain and Loss for Ultrashort Optical Pulses

“…In this paper, there exists a special class of nonlinear wave equations that support soliton solutions in nonlinear physical systems. Propagating solitons through nonlinear directional fiber couplers is an interesting field in optical communication systems [5][6][7][8]. This should not be surprising because the soliton pulses are used as the information carriers (elementary bits) to transmit digital signals over long distances [9].…”
