Abstract

It is now widely accepted that optical media with a quadratic, or χ⁽²⁾, nonlinearity exhibit interesting phenomena which can be exploited in all-optical signal processing (see [1,2] and references dierein). In particular, different types of dichromatic solitary waves (mutually locked fundamental field (FF) and second harmonic (SH)) in conservative quadratic media have been identified and their potential use for signal routing and steering has been discussed [3,4].
