IEEE study highlights cryogenic VCSELs for high-speed optical interconnects

Researchers at the University of Illinois Urbana-Champaign have demonstrated that cryogenic vertical-cavity surface-emitting lasers (cryo-VCSELs) could provide a more energy-efficient method of transmitting data from infrared imaging systems while reducing thermal load. The findings, published in IEEE Photonics Technology Letters recently, address a growing challenge facing advanced infrared focal plane arrays (FPAs…
