Optical solitons of Sasa–Satsuma equation in birefringent fibers

Abstract

This paper studies the propagation of optical solitons of the Sasa–Satsuma model in birefringent fibers. By the complete discrimination system for polynomial, we get three types of optical wave patterns for the model, where singular rational patterns and elliptic functions double periodic patterns are new propagation patterns. Besides, we show the temporal-space structures and propagation properties for some patterns with specific parameter values by drawing graphs. These results are beneficial to study the nonlinear dynamics of optical wave propagation in optics.
