We report ultra-low-power (690fJ/bit) operation of an optical receiver consisting of a germanium-silicon waveguide detector intimately integrated with a receiver circuit and embedded in a clocked digital receiver. We show a wall-plug power efficiency of 690microW/Gbps for the photonic receiver made of a 130nm SOI CMOS Ge waveguide detector integrated to a 90nm Si CMOS receiver circuit. The hybrid CMOS photonic receiver achieved a sensitivity of -18.9dBm at 5Gbps for BER of 10(-12). Enabled by a… CONTINUE READING
