Super-regular breathers for an inhomogenous optical fiber system

Abstract

It is critical to excite pulse wave with higher amplitudes and higher frequencies in optical application. In this work, under investigation is an inhomogeneous fiber system described by a generalized variable coefficient Schrödinger equation. Analytical two-breather solution is obtained through Darboux transformation, a symbolic computation technique. The super-regular breathers can be generated via breathers colliding. The effects of amplitude and frequency amplifications can be observed as the spectral eigenvalue parameters are adjusted.
