WIDEBAND OPTICAL RECEIVER

摘要

PROBLEM TO BE SOLVED: To provide a wideband optical receiver which can receive a high quality frequency multiplexed multi-channel FM signal while reducing group delay distortion, can optically transmit an FM signal subjected to collective FM modulation with a multi-channel signal, and can receive a high rate digital optical signal while suppressing waveform distortion. SOLUTION: A light receiving element 101 and a preamplifier 102 are flip-chip mounted on a multilayer substrate 103 incorporating a capacitive element 109 between a bias terminal 105 and a ground terminal 106.
