Summary:PROBLEM TO BE SOLVED: To reduce crosstalk between adjacent optical systems in a module that collimates, with a lens array, beams emitted by a fiber array, and transmits and receives them.SOLUTION: An optical component of the present disclosure includes a composition to absorb light having a predetermined wavelength (for example, light having an infrared wavelength used for optical communication), has a plurality of linear through-holes 71 formed in parallel at prescribed intervals dwithin a prescribed plane P, and the longitudinal direction of the through-holes 71 is inclined relative to a surface on which one end 71A of the through-holes 71 are arranged. The present disclosure also includes a fiber array module and a light-receiving module including the optical component.SELECTED DRAWING: Figure 2 【課題】本開示は、ファイバアレイから射出されたビームをレンズアレイでコリメートして送受信するモジュールにおいて、隣接する光学系の間でのクロストークを低下させることを目的とする。【解決手段】本開示は、予め定められた波長の光(例えば、光通信に用いられる赤外波長の光)を吸収する組成を有し、直線状の複数の貫通孔71が所定平面PC内に所定間隔dhで平行に形成され、複数の貫通孔71の長手方向は、複数の貫通孔71の一端71Aが配置されている面に対して傾斜していることを特徴とする光部品及びこれを備えるファイバアレイモジュール及び受光モジュールである。【選択図】図2
