Abstract

ABSTR A C T This paper obtains a spectrum of soliton solutions in optical couplers that are with Kerr form of nonlinear refractive index. These are cubic-quartic solitons where the usual chromatic dispersion is replaced by a collective effect of third and fourth order dispersions. Two integration schemes are implemented to recover these soliton solutions.
