英文摘要 | PURPOSE:To prevent remote junction in the region of a light emitting point and to obtain the uniform oscillation yield rate in the surface of a wafer by forcibly inserting a P-AlGaAs remote-junction preventing layer at the upper part of an active layer. CONSTITUTION:A double heterostructure comprising an N-AlGaAs lower clad layer 2, an active layer 3 and a P-AlGaAS upper clad layer 4 is provided on an N-GaAs substrate A semiconductor laser device has said double heterostructure, an N-CaAs current blocking layer 5 and a P-GaAs contact layer 6. In the semiconductor laser device, a P-AlGaAs remote junction preventing layer 9 is inserted between the active layer 3 and the upper clad layer 4. Thus a junction is forcibly formed. In this way, the remote junction due to the fluctuation of P-type dopant in an active region during crystal growing is prevented, the uniform oscillation yield rate in the surface of a wafer is obtained and the temperature characteristic can be improved. |
