Photon-Number-Counting with an InGaAs/InP Avalanche Photodiode by Optical Self-Balancing
Yi Jian, E Wu, Guang Wu, Heping Zeng · 2010
Infrared photon-number-resolving detection was achieved with an InGaAs/InP avalanche avalanche photodiode by using optical self-balancing technique to cancel the spike noise. A photon-number-resolving detection was achieved with the detection efficiency as high as 36%.
