High-speed light source is realized for decoy-state quantum key distribution (QKD) at telecom wavelength of 1.55 μm. By......

We examine the saturation of relative current gain of In0.53Ga0.47As/InP single photon avalanche diodes (SPADs) operated......

This Letter introduces a trigger-controlled Geiger-mode avalanche photodiode (GM-APD). A hierarchical look-back-upon tre......

Ultraviolet (UV) detectors with large photosensitive areas are more advantageous in low-level UV detection applications.......

In this Letter, we report large-area (600 μm diameter) 4H-SiC avalanche photodiodes (APDs) with high gain and low dark ......
