摘要：
In this paper, the existence and stability properties of optical solitons on parity-time (PT) symmetric lattices are investigated. The governing equation for the physical model is the (1 + 1)D cubic-quintic nonlinear Schrodinger equation (CQNLS) with a PT - symmetric potential. The solution to this equation is obtained both analytically and numerically by spectral methods. The numerical existence of fundamental solitons on PT - symmetric lattices is shown for various medium and potential depths. (C) 2015 Elsevier B.V. All rights reserved.
