Highly-Sensitive Infrared Photon Counting by Nondegenerate two-Photon Absorption Under mid-Infrared Pumping (JW1A.104)

Presenter: Yinqi Wang, East China Normal University

Infrared photon detection was realized based on nondegenerate two-photon absorption in silicon, where the mid-infrared pumping scheme significantly enhanced the sensitivity by eliminating background noises due to the harmonic excitation.
