Abstract
【解決手段】光受信モジュール1は、波長多重光を波長に基づいて分波した信号光それぞれを受光する複数のPD29と、該複数のPD29が出力する複数の電気信号を増幅するTIA32と、複数のPD29を搭載するサブマウント30と、を備える。サブマウント30は、複数のPD29とTIA32とを接続する複数の配線と、グランド電位に接続された金属層と、を有し、複数の配線のPD29側の間隔とTIA32側の間隔は異なっており、配線からサブマウント30の厚さ方向に関して最も近い金属層までの距離及び配線の幅は、当該配線の配線長に応じて互いに異なる。
【選択図】図1
Description
図1及び図2は、本発明の第1の実施形態に係る光受信モジュールの一例を示す図である。図1は説明を容易にするためにパッケージの蓋を外し、フレームの一部を破断した状態で示す斜視図、図2(A)は図1(A)の光受信モジュールの断面図、図2(B)は光受信部分の構成を説明するための模式図である。
上述のような部品から構成される光モジュール10は、図2(B)に示すように、O-DeMux26とミラー27が、底壁21から高さ方向に平行に離間したキャリア25の裏面に実装される。そして、レンズアレイ28とPD29は、キャリア25の下方に形成される空間を利用して、上下方向に配列される。すなわち、ミラー27とレンズアレイ28とPD29は、パッケージ12内の上下方向に重なっており、底壁21上に部品搭載スペースを齎す。このスペースに、PD29から出力された電気信号を増幅する増幅器としてTIA32をPD29に近接して配置することが可能となる。
図7は、本発明の第2の実施形態に係る光受信モジュールの一例を説明するため図であり、図7(A)及び図7(B)はそれぞれ本実施形態に係る光受信モジュールのサブマウントの上面及び内部の様子を示す図である。
