ABSTRACT:
The invention is a phase-locked array of CDH-LOC semiconductor injection lasers which has a single, coherent continuous wave output beam. Coupling between elements of the array can occur over long distances because the radiated light wave propagates primarily in the transparent guide layer of the array structure. The elements of the array are then thermally isolated from one another so that continuous wave operation can occur.
