10-Gbps, 5.3-mW Optical Transmitter and Receiver Circuits in 40-nm CMOS
We describe transmitter and receiver circuits for a 10-Gbps single-ended optical link in a 40-nm CMOS technology. The circuits are bonded using low-parasitic micro-solder bumps to silicon photonic… Expand
Ultra-low-energy all-CMOS modulator integrated with driver.
We report the first sub-picojoule per bit (400fJ/bit) operation of a silicon modulator intimately integrated with a driver circuit and embedded in a clocked digital transmitter. We show a wall-plug… Expand
