Cryogenic optical interfacing for scalable quantum computing: analysis of VCSEL operation and thermal profiles as an optical Link

Résumé

Scaling quantum computing while maintaining quantum coherence at cryogenic temperatures is still a challenging issue. It emphasizes the need for an optical link between the control processor in the cryogenic environments and memory units kept in room temperature to mitigate thermal noise-induced decoherence. This study examines the utilization of VCSELs as an optical link in cryogenic environments. The study explores microcavity-gain resonance conditions and their temperature dependency, develops electrical models considering limited thermionic emission, and analyzes internal thermal profiles during low-temperature operation. The research includes characterizing fabricated devices and addressing key factors, such as p-doped DBR, that limit energy-efficient performance.
