We discuss the modeling of self-trapping in arrays of evanescently coupled optical waveguides with Kerr nonlinear response, contrasting two different approaches. Our results show that the coupled mode equations describe with good accuracy, in a wide range of the parameter values of physical interest, the gap soliton self-trapped solutions that can propagate from beams interfering at Bragg angles.

Abstract
We discuss the modeling of self-trapping in arrays of evanescently coupled optical waveguides with Kerr nonlinear response, contrasting two different approaches. Our results show that the coupled mode equations describe with good accuracy, in a wide range of the parameter values of physical interest, the gap soliton self-trapped solutions that can propagate from beams interfering at Bragg angles.File in questo prodotto:
