Abstract

A Kerr medium embedded in a periodic structure exhibits a large variety of interesting features, such as bistability, selfpulsing and chaos, gap solitons and solitary waves. It was found recently, that an intense optical trains can penetrate undistorted through a distributed feedback reflection filter, in spite of the fact that their carrier frequency lies well within a forbidden band of the periodic structure.^[1-4] In this work we extend the discussion of such “ingap” solitary waves to the solitary waves whose carrier frequency of the optical waves may lies far outside the forbidden frequency gap.
