Abstract

Abstract An accurate analysis of graded index optical directional couplers of a kind which could be fabricated by electron beam writing techniques, is presented. Modelling the refractive index profile of the channel waveguides, forming the coupler by a secant hyperbolic function, we have obtained exact expressions describing various characteristics of the directional coupler, including the variation of coupling length with waveguide spacing.
