Hybrid Y-junction laser array
A semiconductor laser array is described, comprising: a plurality of contiguous semiconductor layers, at least one of the layers forming an angle region for lightwave generation; means for injecting current into the active region to produce the lightwaves; means for establishing optical feedback within the laser for the lightwaves sufficient to provide lasing; and a plurality of spaced apparatus waveguides transmitting light generated from the active region, lightwaves propagating in at least some waveguides being directly phase coupled together in a branching coupling region, the waveguides having strong waveguide portions and weak waveguide portions, the strong waveguide portions including the branching coupling region.
