Abstract
【解決手段】 光半導体装置1は、貫通孔3bを有するアイレット3と、複数のリード端子7,9を支持しており貫通孔3bに設けられた絶縁部材5と、アイレット3に支持された第1の部分111、第2の部分112、及び第1の部分111と第2の部分112との間に設けられ絶縁部材上に位置する第3の部分113を有するサブマウント11と、サブマウント11上に搭載された半導体光素子21と、を備えている。

Description
光半導体装置1において、半導体光素子21としてPINフォトダイオードを用いた。このPINフォトダイオードは、80マイクロメートルの受光径を有しており、逆バイアスを15Vとしたときに0.34pFの静電容量Cpを有している。このPINフォトダイオードのアノードとアイレット3との間の静電容量Caは0.26pFであった。また、このPINフォトダイオードのカソードとアイレット3との間の静電容量Ckは0.24pFであった。さらに、サブマウント11の第1導電パターン121及び第2導電パターン122と、第3導電パターン123と、の間の静電容量をCs(pF)として光半導体装置1の静電容量に関する等価回路図を図6(a)に示す。この等価回路図によれば、光半導体装置1のパッケージ全体の静電容量C(pF)は、
C=0.34+(1/(0.24+Cs)+1/0.26)−1 …(式1)
で示される。式1によれば、
Cs=0.3pFのとき、C=0.524pF
Cs=0.2pFのとき、C=0.503pF
Cs=0.1pFのとき、C=0.487pF
Cs=0.08pFのとき、C=0.483pF
である。
従来の光半導体装置701(図7)において、半導体光素子21として上記実施例と同様のPINフォトダイオードを用いた。このPINフォトダイオードのアノードとアイレット709との間の静電容量Caは0.26pFであった。また、このPINフォトダイオードのカソードとアイレット709との間の静電容量Ckは0.24pFであった。この場合の光半導体装置701の静電容量に関する等価回路図を図6(b)に示す。この等価回路図によれば、光半導体装置701のパッケージ全体の静電容量C(pF)は、
C=0.34+(1/0.24+1/0.26)−1 =0.465pFである。
