Scientists make single-photon sources brighter
PhysOrg.com - Evergreen,VA,USA
A research team at the University of California at Santa Barbara (UCSB), headed by Prof. Dirk Bouwmeester (Physics), Prof. Pierre Petroff (Materials and ECE) and Prof. Larry Coldren (ECE), has created a robust micron-sized semiconductor device that can emit single photons on demand at a rate of 31 million photons per second (31 MHz) into an optical fiber, five times better than previously possible.
