Description
1.構成
2.製造方法
3.作用・効果
4.変形例
図1は、本発明の一実施の形態に係る面発光型の半導体レーザ1を斜視的に表したものである。図2は、図1の半導体レーザ1のA−A矢視方向の断面構成の一例を表したものである。なお、図1、図2は模式的に表したものであり、実際の寸法、形状とは異なっている。
本実施の形態の半導体レーザ1は、例えば次のようにして製造することができる。
本実施の形態の半導体レーザ1では、下部電極25と上部電極21との間に所定の電圧が印加されると、電流狭窄層18における電流注入領域18Aを通して活性層13に電流が注入され、これにより電子と正孔の再結合による発光が生じる。この光は、一対の下部DBR層11および上部DBR層15により反射され、所定の波長でレーザ発振を生じ、レーザビームとして光射出口21Aから外部に射出される。
以上、実施の形態を挙げて本発明を説明したが、本発明は上記実施の形態に限定されるものではなく、種々変形可能である。
