Bistability in Optical Waveguides

Abstract

Using a treatment due to Bendow, Gianino and Tzoar (1) in which the electric field of a cw gaussian beam in a nonlinear waveguide is given utilizing the paraxial approximation, it is shown that a bistable behavior can occur in a cylindrically simmetric nonlinear waveguide in which the dielectric constant has a parabolic behavior in the radial direction.
