Conventional couplers including the 2 × 2 directional coupler and the self-imaging multimode interference coupler always produce a 90 ° coupling phase to yield complementary power transfer functions when the relative phase of the two input fields changes. For applications in coupled-cavity lasers, a 2 × 2 half-wave optical coupler with a 180 ° coupling phase is required in order to produce synchronous output power for achieving high single-mode selectivity. We present the designs and optimization of 2 × 2 half-wave couplers, including a three-waveguide directional coupler and a nonimaging multimode interference coupler.
