Abstract :
An analysis is presented of a semiconductor-laser linear phased array which uses a distributed, evanescent-coupled version of Y-junction branches to achieve mode discrimination. As in the Y-junction array, the in-phase fundamental mode has the inherently highest round-trip gain. The advantage of easier mask generation and fabrication for the distributed coupler is offset by its poorer discrimination against higher order modes
