• Abstract: The architecture and component technology of low power, high capacity, short-reach optical interconnect are detailed. Techniques for operating such a system in the presence of changing ambient temperature are addressed. Experiments on a 1 Tbps design are conducted with an optical link experiment indicating sub-pJ/bit energy consumption at scale.
