Description
図1は、実施の形態1に係る光モジュールの内部を示す斜視図である。信号ピン1とモニタピン2,3が導電性のステム4を貫通している。ステム4と信号ピン1,モニタピン2,3の間はそれぞれ絶縁性のガラス5により埋められている。ステム4上にブロック6が搭載され、このブロック6上にサブマウント7を介してレーザーダイオード8が搭載されている。レーザーダイオード8の第1電極は金ワイヤ9を介して信号ピン1に接続され、第2電極はサブマウント7に設けられたビア(図示せず)を介してステム4に接続されている。
図8は、実施の形態2に係る光モジュールを示す断面図である。ステム4とフレキシブル基板16の間にスペーサ37が設けられている。その他の構成は実施の形態1と同様である。スペーサ37により信号線路19とステム4との間隔を広げることで、くり抜き部35における信号線路19とステム4の間の容量を低減し、より高いインピーダンス線路が実現できる。
