Optical solitons in parity-time-symmetric mixed linear and nonlinear lattice with non-Kerr law nonlinearity

This work presents an analytical study of the existence of solitons in non-Kerr law media modulated by the PT-symmetric mixed linear and nonlinear optical complex lattices. Four types of non-Kerr law nonlinearity are taken into account and these are parabolic law, power law, dual-power law as well a...

Summary:This work presents an analytical study of the existence of solitons in non-Kerr law media modulated by the PT-symmetric mixed linear and nonlinear optical complex lattices. Four types of non-Kerr law nonlinearity are taken into account and these are parabolic law, power law, dual-power law as well as polynomial law. With the aid of inverse engineering method, various families of solitons are reported. The presented results are important for describing the propagation of optical solitons in parity-time-symmetric lattices. •Solitons in media modulated by the PT-symmetric mixed complex lattices is studied.•Four types of non-Kerr law nonlinearity are considered.•Various families of solitons are reported.
