Tokyo University of Science Researchers Develop Efficient All-Fiber Single-Photon Source

A research team led by Associate Professor Kaoru Sanaka from the Tokyo University of Science (TUS) has developed a highly efficient fiber-coupled single-photon source. This new method generates single photons directly inside an optical fiber by selectively exciting a single, isolated rare-earth (RE) ion, overcoming high transmission loss issues common in conventional quantum communication systems.
