英文摘要 | PURPOSE:To acquire a BH laser of little leak current bar providing a second semiconductor layer between a semiconductor substrate and an active layer and a third semiconductor layer between the second semiconductor layer and the active layer and by providing a groove which is removed at least as far as the second semiconductor layer to both sides of a light emitting region. CONSTITUTION:After a p-InP buffer layer 20, a p-InGaAsP layer 30, a p-InP layer 40, an undoped InGaAsP active layer 50, an n-InP clad layer 60 are formed one by one on a p-InP substrate 10, a U-shaped groove is formed by Br etching solution. After a photoresist 5 is formed by photolithography, the n-InP layer 60, the InGaAsP 50, and the p-InP layer 40 outside the groove are removed one by one by selective etching. After the photoresist 5 is removed, a p-InP block layer 70, a p-InP block layer 80, an n-InP buried layer 90, an n-InGaAsP contact layer 95 are formed one by one by LPE method. According to this constitution, a leak current flowing to a buried layer can be minimized. |
