A buried heterostructure broad area quantum well heterostructure Al/sub x/Ga/sub 1-//sub x/As-GaAs laser diode modified with a small multiple stripe pattern near its center is described that operates single mode and narrow lobe (<2 /sup 0/) from threshold (I/sub th/) to 2I/sub th/ or 3I/sub th/. The broad area (wide stripe) buried heterostructure laser is made by impurity-induced layer disordering.
