Quantum Dot Single-Photon Detector Is Studied

Facebook X LinkedIn Email
Scientists at Toshiba Research Europe Ltd. and at Cambridge University, both in Cambridge, UK, have demonstrated that single photons may be detected in a quantum dot device by monitoring changes in the resonant tunneling current through a double-barrier structure. Describing the work in the Feb. 18 issue of Physical Review Letters, they report detection efficiencies of 12.5 percent, which they estimate may be improved to approximately 65 percent with optimization of the device structure. The detector is a GaAs NIN diode, with the intrinsic region featuring a double-barrier tunnel structure...Read full article
