ABSTRACT:
A parallel light receiving OEIC comprising a light receiving OEIC layed out in an array form, the light receiving OEIC having an optical fiber fixing groove, provided on a silicon substrate, for efficiently introducing light from an optical fiber into a photodiode, wherein at least one optical fiber fixing groove is provided between light receiving ICs for respective channels. This constitution enables the substantial distance between channels to be increased without increasing the layout area, resulting in reduced interference of noises generated in respective channels with each other, which markedly reduces the influence of crosstalk without increasing the layout area of the parallel light receiving IC.
