Mathematical treatment for soliton-soliton interactions in mono-mode optical fiber

Abstract EN

Mutual interaction of two solitons with equal amplitude ratio (K=1.0) of initial pulse separation (to=3.5pw) propagate in mono-mode optical fiber (30, 90) km is studied analytically.

The examination of propagation of two Solitons with unequal amplitude ratio (10=1.1) initially separated by (to=3.5pw) is studied also.

Results show that solitons of equal amplitude coalesce into one pulse at ¥ =2π and eventually separate to the initial state at and so on.

Launching solitons with unequal amplitude i.

e (K=l.

l) is the simplest way to reduce sol item interaction in order to maintain high bandwidth (10Gbits/s) in communication system.

Also the same study is done numerically using Split Step Fourier Method.
