Figure 1: Level structure of quantum dot and spin manipulation. In order to tackle the large energy difference, we use a frequency downconversion technique that converts a single 910-nm photon into a ...
Geiger-mode avalanche photodiodes (GM-APDs) are highly sensitive light detectors, capable of detecting single photons.
Geiger-mode avalanche photodiodes (GM-APDs) based on 4H-SiC have high single-photon detection efficiency in the deep-ultraviolet (DUV) wavelength. To reliably detect photons in higher wavelengths such ...
