Abstract
PURPOSE:To form a grown layer by one epitaxial growth and to perform a low threshold value and a single mode oscillation by providing a current narrowing layer having a mesa groove in a semiconductor substrate, and laminating an active layer recessed corresponding to the mesa groove thereon through a clad layer. CONSTITUTION:A P-type impurity region 20a is formed in a predetermined diffusion depth on the main surface of a semiconductor substrate 20, a mesa groove 20b is opened at a predetermined part of the region 20a to form a current narrowing layer having a mesa groove 20b. The material of the substrate 20 is made of III-V or II-IV compound semiconductor. A first clad layer 21 to contact layer 24 are formed by a series of one epitaxial growth. It can prevent a regrown boundary in a plurality of epitaxial growths from damaging, a current is narrowed by the region 20a to oscillate in a single basic lateral mode.
