An APD/FET Optical Receiver Operating at 8 Gbit/Sec

1 January 1987

A high-sensitivity optical receiver has been designed for a bit rate of 8 Gbit/sec and wavelengths from 1.3micron to 1.55micron. The receiver uses a 60 GHz gain-bandwidth-product InGaAs/InGaAsP/InP avalanche photodiode followed by a high-impedance hybrid GaAs MESFET preamplifier.
