Avalanche Photodiodes (APDs), particularly Silicon APDs (Si-APDs) and Indium Gallium Arsenide APDs (InGaAs-APDs), are widely deployed. Si-APDs are favored for their high quantum efficiency and low dark counts in the visible and near-infrared spectrum, benefiting from mature silicon fabrication processes. InGaAs-APDs extend detection into the longer infrared wavelengths (1000-1700 nm), which is critical for fiber-optic communications and eye-safe LiDAR, though they generally exhibit higher dark counts than their silicon counterparts and often require active cooling. Superconducting Nanowire Single-Photon Detectors (SNSPDs) represent the pinnacle of SPD performance, boasting near-unity detection efficiency (over 90%), picosecond-level timing jitter, and ultra-low dark count rates. These attributes make them indispensable for cutting-edge quantum experiments and long-distance quantum communication. However, their reliance on extremely low cryogenic temperatures, typically achieved using complex and costly cryocoolers (e.g., closed-cycle Gifford-McMahon or pulse tube cryocoolers), presents a significant operational and financial challenge, limiting their broader commercialization. Silicon Photomultipliers (SiPMs), often referred to as Geiger-mode Avalanche Photodiodes, are arrays of numerous tiny APD microcells operating in Geiger mode. They offer high internal gain, the ability to resolve the number of incident photons, and can operate at room temperature or with modest thermoelectric cooling, making them attractive for applications like PET medical imaging, LiDAR, and scintillator readout due to their compactness and cost-effectiveness. Traditional Photomultiplier Tubes (PMTs), while a more mature technology, still hold relevance due to their large active area, very high gain, broad spectral response, and extremely low dark counts, particularly useful in scientific instruments and spectroscopy. Beyond these core detector types, the technological landscape encompasses a host of critical enabling and supporting technologies.
