PHASE-LOCKED LASER ARRAY HAVING A NON-UNIFORM SPACING BETWEEN LOSING REGIONS ABSTRACT OF THE DISCLOSURE A phase-locked semiconductor array wherein the lasing regions of the array are spaced an effective distance apart such that the modes of oscillation of the different lasing regions are phase-locked to one another. The center-to-center spacing between the lasing regions is non-uniform. This variation in spacing perturbs the preferred 180° phase difference between adjacent lasing regions thereby providing an increased yield of arrays exhibiting a single-lobed, far-field radiation pattern.
