| 英文摘要 | PURPOSE:To provide a semiconductor laser having a small astigmatism. CONSTITUTION:An n-type clad layer 2, an active layer 3, a p-type inner clad layer 4, a p-type etching stopper layer 5, and a p-type outer clad layer 6 are sequentially formed on an n-type GaAs substrate Part of the layer 6 is etched to form a mesa, and then a current block layer 7, a low resistance layer 8, a buffer layer 9 and a contact layer 10 are sequentially formed. The layers 7, 8 have larger band gaps than that of the active layer and cannot absorb light emitted from the active layer, and hence its astigmatism can be reduced. |
