Phys. Rev. A 78, 025804 (2008) [4 pages]High-efficiency photon-number-resolving multichannel detectorReceived 9 April 2008; published 18 August 2008 A balanced eight-port photon-number-resolving detector is developed. The employed scheme is based on an optical-fiber time-multiplexed device with the unique total optical transmittance reaching 93% and a pair of avalanche photodiodes. The balanced operation is achieved even for imperfect unbalanced fiber splitters used in the time-multiplexed device. The complete characterization of the detector for both classical and single-photon signals is presented. High-speed photon counting at the rates of 100 kHz with the total detection efficiency exceeding 50% is verified. © 2008 The American Physical Society URL:
