Abstract

An analysis of asymmetric directional couplers consisting of two parallel slab waveguides has been performed using the improved coupled-mode theory for multimode waveguides. The use of such couplers for multibranch power dividers has been illustrated, and the expected performances have been discussed, both for a two-branch divider and a three-branch one. One notes in particular the high SNR and efficiency at the end of the coupling region.
