Abstract
PURPOSE:To reduce the coherency of a laser beam and to obtain high reliability by forming an electrode stripe width narrower than the width of a groove. CONSTITUTION:A parallel V-shaped groove is formed in a plane (D1-1), for example, 5mum or width and 2.0mum of depth with an etchant of NH4OH on an n-type GaAs substrate 1. Then, grown layers 2, 3, 4, 5, 6, 7 are sequentially grown by a liquid growth method. The layers are 0.2, 0.3, 0.08, 0.3, 1.0, 0.7mum thick in this order on a flat part. The n-type clad layer 2 is not flat on the groove in the part of a guided groove 11, and a structure of a thick photoconductive layer 3 is formed at a light emitting section. Further, with an SiO2 as a mask a P<+> type diffused layer 8 of 3mum of thickness is formed on a light emitting region, and a P-type electrode 10 and an N-type electrode 9 are formed.
