英文摘要 | PURPOSE:To decrease a self-excited oscillation frequency by a method wherein the thickness and the width of a multi-quantum well layer are specified and the well layer is doped with a n-type impurity. CONSTITUTION:The following are successively formed in lamination on a substrate 1: a buffer layer 2; a clad layer 3; a multi quantum well structure active layer 4'; a clad layer 5; a current constricting layer 7; and a buried layer 8. The adequate thickness and well width of the active layer 4, are 0.05-0.09mum and 5-20nm respectively. Here, the active layer 4, is doped with n-type impurity Se, and a quantum barrier. layer 5 and a quantum well layer 4 are repeatedly and uniformly doped with also n-type impurity Se. If the active layer 4' is doped as mentioned above, electrons contributing the recombination luminescence can be supplied without the injection of carriers, and the gain can be obtained throughout a wide energy region. In result, a self excited oscillation frequency can be decreased. |
