Title

Analysis Of A Three-Core Adiabatic Directional Coupler

Abstract

We present an analytical description of a new class of three-core adiabatic following directional couplers. Using a multiple-scale WKB method we obtain closed-form expressions describing the optical field dynamics in such structures. The adiabatic evolution occurring in this particular three-core configuration can lead to a spatial switch over of local supermodes and to an irreversible power transfer. © 2009 Elsevier B.V.
