Inelastic collision and fusion of optical solitons in dispersion oscillating fiber

Abstract

We show through numerical simulations that dispersion oscillating fibers can be used for the fusion of fundamental solitons into high-intensity pulse. Three particular cases are considered: fusion of two co-propagating fundamental solitons, fusion of three co-propagating fundamental solitons and merge of two colliding solitons into breather bound state. Generation of high-intensity pulse is associated with the formation of distinct high-amplitude soliton.
