On a new approach to optical solitons in dielectric fibers

Abstract

In this letter we describe a new and simple approach for modulating the electromagnetic wave propagating in a dielectric medium in the form of solitons by considering the torque developed between the induced dipoles in the medium and external field without taking into account the nonlinear Kerr effect. A reductive perturbation method deduces the Maxwell equation coupled with the Larmor equation of the torque to the derivative nonlinear Schrödinger equation that admits optical solitons in the medium.
