英文摘要 | PURPOSE:To prevent a high-frequently current from leaking out through the junction capacitance of a current blocking section when high-frequency modula tion is performed on a semiconductor laser used for an optical disk device, etc., for preventing the generation of noise. CONSTITUTION:Crystals of an n-Al0.5Ga0.5As clad layer 2 (5mum), undoped Al0.14Ga0.86As active layer 3 (0.04mum), p-Al0.5Ga0.5As clad layer 4 (5mum), and p-GaAs contact layer 5 (0.3mum) are successively grown on an n-GaAs substrate Then the layers 4 and 5 are processed to a ridge-like shape and a clock layer composed of an n-GaAs layer 6 (0.8mum) and undoped GaAs layer 7 (0.3mum) is formed. Finally, the structure shown in Fig. 1 is formed by growing a p-GaAs buried layer 8 (2mum). The laser chip of this semiconductor laser is formed by providing Au electrodes 9 on the surface and rear of the semiconductor wafer thus manufactured. |
