High Speed PIN Photodiodes for 10 - 20 Gbit/s High Sensitivity Photoreceivers

This paper describes photodiodes developed for bit rates of 10 to 20 Gbit/s, obtained by compromising absorption thickness, capacitance and optical fibre coupling. Their fabrication is described, their characteristics are given, and illustrated by the realization of high speed high sensitivity photoreceivers at 10 and 20 Gbit/s.
