英文摘要 | PURPOSE:To stop current leakage from a coupling part and achieve a large output by providing a current block layer below a lower clad layer near the end face of a resonator and at the same time by coupling an activation region with a window region using a high-resistance layer over the entire surface. CONSTITUTION:Carriers injected from a p-side electrode 8 are injected into an activation region 5. However, although they may flow through the interface at a coupling part when a large number of them are injected since a p-GaAs cap layer 7 has low resistance, there is substantially no leakage current through a light guide layer 4 in a window region since an n-type semiconductor layer where Ga ion is injected has high resistance. On the one hand, resistance of a p-type semiconductor layer is reduced after annealing even if the Ga ion beam is injected. On the other hand, since a current block layer 2 is provided at the lower layer of an n-type Al GaAs clad layer 3 of the window region and the coupling part, current leakage at the coupling part and the window region is greatly restricted. |
