ABSTRACT:
A semiconductor optical element includes a semiconductor layer on a semiconductor substrate, a plurality of parallel stripe-shaped grooves in the layer having widths sufficiently narrow to produce a quantum effect and spaced at an interval sufficiently narrow to produce a quantum effect in a semiconductor layer disposed between adjacent grooves, and a structure including alternating semiconductor quantum well and barrier layers disposed on the semiconductor layer in which the quantum well layer thickness is less than the depth of the grooves and sufficiently thin to produce a quantum effect and the barrier layer thickness is larger than the depth of the grooves, the quantum well and barrier layers being alternatingly disposed on the semiconductor layer in the grooves and on regions between adjacent grooves.
