Formation of chirped solitons when a femtosecond pulse passes through a layer with an inhomogeneous refractive index in a medium with cubic nonlinearity

Abstract

A way of forming a new class of solitons—chirped (or aberrational) solitons—when a pulse passes through a layered nonlinear structure in a cubically nonlinear medium is demonstrated by means of computer simulation. It is shown that the pulse frequency modulation of the resulting solitons is nonlinear.
