IPC: H01S5/00
Filed: 1984-07-30
Abstract: PURPOSE:To fabricate the buried type laser of double hetero junction by one process of epitaxial growth by forming an electric current blocking layer on the main surfaces on both sides of the step part arranged on a semiconductor substrate. CONSTITUTION:On the first and second main surfaces on both sides of a step part on the N type semiconductor substrate 17 of forbidden band width E1 comprising a step part, the first and second semiconductor layers 18 and 19 of P type having forbidden band width E2 and E3 respectively are formed. Furthermore, the P type third semiconductor layer 20 having forbidden band width E4 is formed on the plane of step part with contacting with the layer 19. Among the forbidden bands, E1, E2, E4>E3. Then if the layer is constituted of N type, the layers 18 and 19 on the first and second main surfaces become P-N junction, however, the layer 20 and the substrate 17 in the step part become N-P junction oppositely. Accordingly, when the step part is biased in forward direction, the current flows into only the step part and the light emission at the step part becomes possible.
