Paper Abstract

Directional couplers can be formed by two identical (symmetrical couplers) or nonidentical (asymmetrical coulers) waveguides. The overlap of their evanescent field causes transfer of guided energy from one waveguide to the other. Complete energy transfer can take place if the propagation constant of modes is the same in both waveguides. Directional couplers form the basis for many devices such as wavelength filters, switches, modulators and power dividers. In this work we have analyzed symmetrical and asymmetrical slab directional couplers in glass and GaAs substrates. Here, we report on the study of performance of these devices as wavelength filters. Analysis of directional coupler switches and power dividers will be also presented in the conference.
