Description
図4に示す光コンポーネントは、ハウジング113と、その内部に光ファイバ端面での反射を抑制するためのブロック部材であるガラスブロック111と、ガラスブロック111をハウジング113に固定するためのマウント部材112と、から構成されている。マウント部材112には側面に複数の突起部114を有しており、この突起部114とハウジング113が圧入されることで、ガラスブロック111を固定している。その際、突起部114が弾性変形することによって、ガラスブロック111に過大な応力を加えることなくガラスブロック111を固定することができる。
また、ガラスブロック2の他の形態として、光デバイス側の端面の中央部(光が通過する個所、ハウジング3に対して押し付けられる面以外の面)のみを、光ファイバの光軸に対して数度(約5°〜10°程度)傾斜させた構造にしてもよい。
Claims (2)
- 光コネクタの光ファイバ端面での反射を抑制する光コンポーネントであって、
光コネクタをガイドするスリーブと、該ガイドされた光コネクタの光ファイバ端面での反射を抑制するブロック部材と、前記スリーブ及び前記ブロック部材を保持するハウジングとを有し、
該ハウジングは、前記光コネクタから前記ブロック部材にかかる荷重を受けるための押さえ部を有し、
前記スリーブ端部に形成された開口部に前記ブロック部材を収容し、該スリーブ端部を前記ハウジングの開口部に圧入固定する際に、該圧入固定時の荷重が前記ブロック部材の外周面に直接加わらないように、前記スリーブ端部の開口部内周面と前記ブロック部材の外周面との間に隙間を有することを特徴とする光コンポーネント。 - 前記ブロック部材は、光デバイス側の端面の中央部が光軸に対して傾斜していることを特徴とする請求項1に記載の光コンポーネント。
