All optical switches for optical soliton interactions in a birefringent fiber

Abstract

The interactions of optical solitons can be used to develop photonic information processing devices such as all optical switches and all optical logic gates. It is the key to achieving high-speed, high-capacity all optical networks and optical computers, and has important academic value. This paper is based on the coupled nonlinear Schrödinger equations to study the properties of all optical switches of optical solitons in birefringent fibers. Through the researches, it was found that different initial conditions can achieve all optical switching function, and the influence of different physical parameters of birefringent fibers on all optical soliton switching was studied. The relevant conclusions are conducive to achieving the all-optical switching function of optical solitons in birefringent fibers, providing useful guidance for the widespread application of optical soliton all-optical switches in birefringent fibers in fiber communications.
