Using SPADs in a CMOS process, we are implementing circuits for fast optical communications. It is hoped that SPAD dead-time can be reduced by a combination of next generation single-photon devices, new active quenching circuits and by device multiplexing techniques. Optical pulses derived from the MicroLEDs can be received by an array of multiplexed single-photon devices. Which (with low detector noise rates) will provide high speed and low error optical communications in a fraction of the area of current avalanche photo-diode communications systems.
