1.5mW/Gbps Low Power Optical Interconnect Transmitter Exploiting High-Efficiency VCSEL and CMOS Driver

We demonstrate a low power optical interconnect transmitter which employs a 990 nm VCSEL with high efficiency and low threshold current, and a 130 nm CMOS driver. The power dissipated by the transmitter is 15.1 mW at 10 Gbps.
