    • PURPOSE:Not only to obtain a laser excellent in current constriction, low in threshold value, and high in reliability but also enable the mass production of the laser at a low cost by a method wherein ion implantation is performed into the part of an intermediate band gap layer other than a current injection region. CONSTITUTION:An n-GaAs buffer layer 102, an n-(Al0.5Ga0.5)0.5In0.5P clad layer 103, an undoped Ga0.5In0.5P active layer 104, a p-(Al0.5Ga0.5)0.5In0.5P clad layer 105, a p-Ga0.5In0.5P intermediate layer band gap layer 106, and a p-GaAs contact layer 107 are formed on an n-GaAs substrate 101. And, protons are injected into both the sides of a stripe through an ion-implantation so as to penetrate the intermediate band gap layer 106 (as shown by region 108), a p-type electrode 109 is formed on the RGaAs contact layer 107, and an n-type electrode 110 is formed on the substrate 101 side. When a current is made to flow through this laser, the oscillation occurs at the active layer 104 in width nearly equal to that of the stripe. Therefore, the current is completely prevented from spreading in the RGa0.5In0.5P intermediate band gap layer 106, so that the oscillating threshold is low.
