ABSTRACT:
A method and apparatus for phase-locking semiconductor laser arrays is described wherein individual light waves propagating in adjacent waveguides are phase-locked by intercoupling the waveguides in a specific manner. The waveguides are intercoupled in an unguided mode-mixing region wherein various modes of propagation mix by diffraction. The length of this region is fixed at a distance z which produces a phase difference an integral multiple of 2.pi. between adjacent waveguides.
