ABSTRACT:
A monolithic laser device produces a plurality of spatially displaced emitting cavities in an active layer of a semiconductor body acting as a waveguide for light wave propagation under lasing conditions. Various means are disclosed to deflect and directly couple a portion of the optical wave propagation into one or more different spatially displaced emitting cavities to improve coherence and reduce beam divergence.
