Abstract

The dynamics of bistable soliton propagation and switching in a fiber whose intensity-dependent refractive index is described by the linear plus smooth-step model is numerically investigated under conditions where the fiber is evanescently coupled to an identical, initially empty, parallel fiber. The initially empty fiber can perform a number of useful operations on solitons in the first fiber, which could be of interest in optical device design.
