"Efficient Room Temperature Operation of Germanium-Silicon Single-Photon Avalanche Diode"

Researchers have achieved room temperature operation of a germanium-on-silicon single-photon avalanche diode (SPAD), a key component in photonics and quantum applications. This advancement is significant as it enables the practical integration of SPADs into various technologies, such as quantum communication and imaging systems, without the need for cryogenic cooling. The development opens up new possibilities for high-performance photon detection and imaging at room temperature, paving the way for more widespread and accessible applications in the field of photonics.
