0.5 mu m CMOS technology is used to drive oxide-confined low-threshold
current vertical cavity surface emitting laser diodes at 2.5Gbit/s. T
he 7 mW power consumption for the optoelectronic transmitter is twenty
times less than a 3.6V electronic positive emitter coupled logic tran
smit circuit and four times less than a 3.6V electronic low voltage di
fferential signal transmit circuit.
