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.
