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 all values of competing parameters. (C) 2017 Elsevier GmbH. All rights reserved.
