Abstract

PURPOSE:To perform stable basic lateral mode oscillation by forming a groove on a clad layer on an active layer, forming a guide layer in contact with the side of the groove of the clad layer and suppressing the increase of the threshold current value due to the leakage of the carrier. CONSTITUTION:An active layer 11 and a clad layer 12 are grown in liquid phase on a substrate 10. A groove is so formed in a stripe shape on the layer 12 vertically to the cleavage surface. Thereafter, a guide layer 13 is grown on the clad layer to fill the groove. After an SiO2 film 14 is formed, a striped window is so opened as to include the groove, and Cd is diffused in the layer 15. Subsequently, a P type ohmic contact 16 and an N type ohmic contact 17 are formed.
