Description
図1は、APD301を説明する素子の模式図である。図1(a)は上面図であり、図1(b)は断面図である。なお、本明細書では、半絶縁性基板1に対し、n電極9側を上側及び積層方向として説明する。
図5は、APD302を説明する素子の模式図(断面図)である。APD302と図1及び図2のAPD301との違いは、APD302がn形電極層8Bの代替としてn形電極層28Bを備えている点である。n形電極層28Bは、n形電極層8Bと形状が異なる。すなわち、積層方向から見て、n形電極層28Bの外周はn形電極バッファ層8Aの外周の内側にある。
実施形態1及び2において、InAlAsをなだれ増倍層、InGaAsを光吸収層とするAPD(301、302)の例を述べたが、半導体材料の種類を制限するものではない。APD(301、302)で説明した構造は、他の半導体材料の組み合わせによるAPD素子においても同様に適用することができる。
