Description
図1は第1の実施の形態の光モジュールの一例を示す構成図で、図1(a)は平面図、図1(b)は図1(a)のA−A断面図、図1(c)は図1(a)のB−B断面図である。
次に、第1の実施の形態の光モジュールの動作例について説明する。ドライバIC17から出力された電気信号は、ボンディングワイヤ19を通って面型発光素子4に入力され、面型発光素子4は、電気信号を光信号に変換して出射する。
図3は第2の実施の形態の光モジュールの一例を示す構成図で、図3(a)は平面図、図3(b)は図3(a)のC−C断面図である。
次に、第2の実施の形態の光モジュールの動作例について説明する。ドライバIC17から出力された電気信号は、ボンディングワイヤ19を通って面型発光素子4に入力され、面型発光素子4は、電気信号を光信号に変換して出射する。
図4は第3の実施の形態の光モジュールの一例を示す構成図で、図4(a)は平面図、図4(b)は図4(a)のD−D断面図である。
第3の実施の形態の光モジュール1Cにおいて、光信号を送受信する動作は第2の実施の形態の光導波路モジュール1Bと同じである。第3の実施の形態の光モジュール1Cでも、面型発光素子4を駆動する電気信号がドライバIC17から面型発光素子4にボンディングワイヤ19を通って送電される際に、ボンディングワイヤ19から電磁放射を生じる。
以上説明した第1の実施の形態の光モジュール1Aと第2の実施の形態の光モジュール1B及び第3の実施の形態の光モジュール1Cでは、光素子として発光素子と受光素子を1個ずつ備えた光送受信モジュールを例に示したが、受光素子を備えず、複数の発光素子を備えて構成される光送信モジュールでも良い。また、発光素子を備えず、複数の受光素子を備えて構成される光受信モジュールでも良い。更には、複数の発光素子と複数の受光素子を備えて構成される光送受信モジュールでも良い。このように、複数個の光素子を使用した色々な形態の光モジュールにおいて、同様の構成によってクロストークの低減を実現することができることは言うまでもない。
