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 power efficiency below 400µW/Gbps for a 130nm SOI …

An Ultra-Low Power All CMOS Si Photonic Transmitter

We report the first 400fJ/bit all-CMOS silicon photonic transmitter made of CMOS depletion ring modulator flip-chip integrated with CMOS driver, and demonstrated error-free 5Gbps transmission of over 1.5Pbits of data without closed-loop ring …
