Highly sensitive detection for infrared photons by non-degenerate two-photon absorption under mid-infrared pumping
Jianan Fang, Yinqi Wang, Ming Yan +3
We have demonstrated highly-sensitive photon counting in the infrared based on the two-photon absorption (2PA) in a silicon avalanche photodiode, where the required photon energy f…
