Solid-state lasers of new type contain pseudomorphic In0.15Ga0.85As single-quantum-well (SQW) active layers sandwiched between thinner layers of GaAs that, in turn, are sandwiched between graded-index-of-refraction separate-confinement-heterostructure (GRINSCH) layers of AlxGa1-xAs. Lasers emit edgewise as other solid-state lasers, or made to emit perpendicularly to their surfaces by use of integrated 45 degree beam deflectors that deflect edge-emitted light. Suitable for incorporation into optoelectronic integrated circuits implementing optical interconnection and parallel processing of data.
