Abstract: Abstract We investigate the existence and stability of two dimensional nonlinear localized modes in parity-time symmetric optical media with self-focusing/self-defocusing cubic and quintic nonlinearities. The exact analytical form of the localized modes is found for…

Abstract: Abstract We investigate the existence and stability of nonlocal surface solitons at the interface between linear media and nonlocal nonlinear media with two-dimensional (2D) parity-time ( PT )-symmetric optical lattices. We analytically obtain the nonlinearity-induced…

Abstract: Achieving exact balance between spatially separated gain and loss is generally regarded as a necessary condition for parity–time (PT)-symmetric optical systems [1]-[12]. We introduce generalized PT (gPT)-symmetric optical structures, which have an asymmetric and unbalanced…
