英文摘要 | PURPOSE:To reduce leakage current and simplify production process by selectively growing an n-type semiconductor clad layer, an active layer, a p-type semiconductor clad layer at the inside of groove only so that the upper edge of groove becomes flat and by growing the p-type semiconductor clad layer over the entire surface finally. CONSTITUTION:The upper and lower sides of either of an active area and a semi- insulation current rejection layer provided at both left and right of the active area are enclosed by the p-type semiconductor clad layer and n-type semiconductor clad layer, respectively. Also, an n-type semiconductor layer is inserted being adjacent to the p-type semiconductor clad layer on the upper surface of the semi-insulation current rejection phase. For example, an n-type InP substrate 10 consists of a semi- insulation InP current rejection layer 11, an n type InP clad layer 12, an InGaAsP active layer 13, a p-type InP clad layer 14, and an n-type InP stopper layer 15 and the n-type InP stopper layer 15 directly contacts a p-type InP clad layer 14. In this case, a layer consisting of InGaAsP composition is not provided on the semi-insulation InP current rejection layer 11 to reduce current leakage. Thus, a semiconductor laser with a low threshold current and with high-efficiency oscillation suiting for light source elements for optic communication and optic information processing can be realized. |
