Solitones no autónomos en fibras ópticas

Abstract

Soliton solutions of the non-linear Schrödinger equation of variable coefficients which describe many real cases of solitonic propagation can be obtained by means of the `designable integrability' mapping to the standard non-linear Schrödinger equation of constant coefficients proposed by He and Li. In this paper, this method of obtaining the non-autonomous soliton solutions is presented for the general case of optical fibers with gain/loss, and applied to fibers with amplifiers, and those allowing the propagation of bright solitons.
