Abstract This paper studies soliton solutions in parity-time-symmetric mixed linear and nonlinear optical lattices with Kerr and non-Kerr law nonlinearities. Four different kinds of rough mediums namely, parabolic law, power law, dual power law and polynomial law are considered in the context of non-Kerr media. With the help of the inverse engineering scheme, different types of soliton solutions are presented. The extracted outcomes show that exact bright and dark soliton solutions can exist for those different physical states.
