Optical solitons in media with focusing and defocusing saturable nonlinearity and a parity-time-symmetric external potential

We report results for solitons in models of waveguides with focusing or defocusing saturable nonlinearity and a parity-time ([Image: see text])-symmetric complex-valued external potential of the Scarf-II type. The model applies to the nonlinear wave propagation in graded-index optical waveguides wit...
