Analysis of a three-core adiabatic directional coupler
Abbreviated Journal Title
MODE THEORY; Optics
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. (C) 2009 Elsevier B.V.
