英文摘要 | PURPOSE:To accelerate the resistance increase of a buried layer thereby to obtain a high resistance buried type semiconductor laser having small efficiency of a threshold current by providing a bandlike structure having an active layer and a single hetero structure on an optical guide layer to be buried. CONSTITUTION:A bandlike structure having a single hetero junction structure made of an active layer 14 and a semiconductor layer 15 including a forbidden band width wider than the layer 14, and a double hetero junction formed on an optical guide layer 13 provided through a clad layer 12 on one main surface of a semiconductor substrate 1 with an Fe-doped buried layer 17 of a high resistance semiconductor including forbidden band width wider than the layer 14 provided on the side of the structure are formed. A leakage current can be reduced to the degree of no problem by doping Fe in the layer 17. Since a single traverse mode oscillation can be executed even if the width of the layer 14 is increased, the adverse influence of the Fe can be avoided. Thus, a high resistance buried type semiconductor laser which has high light emitting efficiency can be obtained. |
