ABSTRACT:
A phase-locked semiconductor laser array includes a plurality of channels in a surface of a substrate with lands therebetween with laser oscillation occurring in the cavity region over each of the channels. The individual oscillators are coupled by the overlap of their evanescent fields to produce a phase-locked array. Phase-shifting means are included in alternate channels to ensure that the laser light emitted by the different lasing regions are in phase with one another. Preferably the phase-shifting means comprise portions of each of alternate channels having a different spacing from the cavity region than that of the remainder of the channels.
