英文摘要 | PURPOSE:To enhance an output by providing a light enlarging layer having a refractive index larger than that of a clad layer and smaller than that of an active layer in the clad layer. CONSTITUTION:An n-type GaAs buffer layer 2, an n-type AlGaAs clad layer 31, an n-type AlGaAs light enlarging layer 4, an n-type AlGaAs clad layer 32, an undoped quantum well active layer 5, a p-type AlGaAs clad layer 6 and a p-type GaAs layer 7 are sequentially crystalline grown on an n-type GaAs substrate Thereafter, a stripelike upper SiO2 dielectric film is formed by a photolithography and a CVD, the p-type clad layer is etched to form a ridge. Then, an n-type GaAs block layer 8 and a p-type GaAs buried layer 9 are selectively grown, a Cr-Au electrode 10 is deposited on the crystalline surface, an AuGeNi-Cr-Au electrode is deposited on a rear surface, cleaved and scribed. Thus, an optical breakdown output limit of an end face of a laser is improved, and output is enhanced. |
