英文摘要 | PURPOSE:To narrow the width of a current injection region, to lower a threshold current value and to stabilize laser oscillation by forming a projecting section in which the width of a lower section is made narrower than an upper section. CONSTITUTION:An N-type clad layer 3, an active layer 4, a P-type clad layer 5 and a P type cap layer 6 are grown successively onto the face (100) of an N-type GaAs substrate 2. A resist is shaped so that the striped direction is directed in , and etching is conducted by an etchant at the ratio of H2SO4:H2O2:H2O=1:8: Consequently, the side faces of a projecting section left under the resist are represented by a face (1-11) and a face (11-1), and the striped projecting section 5 in which a lower section is made narrower than an upper section is formed. An SiO2 layer 8 is shaped, the SiO2 layer on the layer 6 is removed, and electrodes 1, 7 are formed. Since the width of the lower section of the projecting section 5 is narrowed, current injection width can be narrowed. Sections except the cap layer 6 are coated with the SiO2 layer 8, thus also preventing leakage currents. |
