Energy-per-bit advantages of chip-scale hybrid-integrated optical interconnects using surface-normal electro-aborption MQW modulators

A hybrid MQW/EAM-based chip-scale photonic interconnect concept is projected to achieve significantly lower energy-per-bit performance than monolithically integrated Si-Photonic and directly-modulated VCSEL approaches - enabling bandwidth density to scale with foreseeable high performance computing CMOS technology.
