Description
図1は、実施形態のフォトリレーの模式斜視図である。図2は、実施形態のフォトリレーの模式断面図である。
受光素子50は、制御回路50aをさらに有することができる。制御回路50aは、フォトダイオードアレイ50bの第1の電極と、第2の電極と、にそれぞれ接続されている。このような構成とすると、ソース・コモン接続されたMOSFET70のそれぞれのゲートに電圧を供給できる。また、制御回路50aは抵抗などを含み、MOSFET70がオンからオフに転じる場合に放電させて立ち下がり時間を短縮することができる。
縦軸はインサーレションロス(dB)、横軸は周波数(Hz)である。実線は、ポリイミド基板10の厚さが25μmのフォトリレーの高周波通過特性である。点線は、ポリイミド基板10の代わりに400μm厚のガラスエポキシ基板を用いたフォトリレーの高周波通過特性である。インサーレションロスは、10MHzのときの通過特性を基準としている。10GHz近傍では、ポリイミド基板10のフォトリレーとガラスエポキシ基板とで大きな差は無い。しかし、ガラスエポキシ基板を用いたフォトリレーは20数GHzを谷底とする約-20dBの大きな損失があり、約13GHzで損失が-3dBに到達している。一方、ポリイミド基板10を用いた場合、10GHzから30GHzにかけてゆるやかに損失が増大し、損失は大きくても-5dBという極めて優れた高周波通過特性を有することが分かる。
