摘要

Vertical cavity surface emitting lasers operating at 4.2K are developed for energy efficient optical links between cryogenic systems and room-temperature data storage systems. Design considerations, material models, and validation of required electro-optical-thermal models are presented. Successful operation at mA-level injection is demonstrated.
