Abstract

This study demonstrates that the excitation of the first-order mode in access waveguides can significantly deteriorate the coupling ratio of unbalanced MMI couplers and increase the excess losses. Care, therefore, should be taken in coupling light into the access waveguides, as well as in the circuit design to avoid this effect. Another option for this, as measurement results suggest, is controlling the relative phase difference.
