英文摘要 | PURPOSE:To achieve a low threshold value by providing a pair of second ridge regions closely so that a first ridge region is held and by controlling making a groove wherein the gap between the groove bottom and active layer is surrounded by both ridges into V groove. CONSTITUTION:An N-type GaAs clad layer 2a, an AlGaAs active layer 3a, a P-type AlGaAs clad layer 4a, and a P-type GaAs layer 5 are allowed to grow on an n-type GaAs (100) substrate 1 and then an SiN film coated. Then, SiN films 13a and 13b of a specified region 3 are left and the other SiN films are removed. Then, a P-type GaAs layer 5 is removed within a liquid of NH4 OH:H2O2=1:25 and the AlGaAs clad layer 4a is etched where H2SO4:H2O2:H2O is equal to 3:1: Then, after removing the projecting part of the central SiN film 13a with hydrofluoric acid etching liquid, a current block layer 24 consisting of an n-type AlGaAs layer 21, a P-type AlGaAs layer 22, and an n-type GaAs layer 23 is embedded. Then, after removing an SiN film 13a with hydrofluoric acid etching liquid, a P-type GaAs contact layer 25 is allowed to grow. It allows the gap between the groove bottom and the active layer to be precisely controlled and a desired characteristics to be achieved with improved reproducibility. |
