Abstract
Description
図1は、実施の形態1に係る光半導体装置を示す正面側斜視図である。図2は、実施の形態1に係る光半導体装置を示す背面側斜視図である。図3は、実施の形態1に係る光半導体装置の内部を示す上面図である。
図11は、実施の形態2に係る光半導体装置を示す正面側斜視図である。図12は、実施の形態2に係る光半導体装置を示す背面側斜視図である。図13は、実施の形態2に係る光半導体装置の内部を示す上面図である。
図15は、実施の形態3に係る光半導体装置を示す正面側斜視図である。図16は、実施の形態3に係る光半導体装置を示す背面側斜視図である。図17は、実施の形態3に係る光半導体装置の内部を示す上面図である。
図19は、実施の形態4に係る光半導体装置を示す断面図である。レンズキャップ19のレンズが平板ガラス20である。このため、レンズと半導体光変調素子13の位置関係がずれたとしても、焦点距離又は結合効率などの光学特性に影響がないため、レンズキャップ19の構造ばらつきと実装精度を緩和することができる。その他の構成及び効果は実施の形態1と同様である。
