As quantum sensing applications move toward commercialization, compact and efficient laser sources at rubidium wavelengths are becoming increasingly important. This paper presents Modulight’s 780 nm and 795 nm VCSEL technologies, optimized for applications such as vapor-cell magnetometers where low power consumption, small size, and stable performance are critical. The authors discuss wafer-level manufacturing techniques, polarization control, and production scalability for high-yield quantum sensing solutions.
