제목 단일광자검출기의 최근 연구동향 (Recent Research Progress in Single-Photon Detectors)
초록 Single-photon detectors are very useful devices/sensors in a large number of applications, including light detection and ranging (LiDAR), time of flight (ToF), biomedical, and quantum applications. Examples include advanced driver-assistance systems (ADAS), autonomous vehicles, drones, robots, rovers, space navigation, 3D face and gesture recognition, TOF positron emission tomography (TOF PET), fluorescence-lifetime imaging microscopy (FLIM), super-resolution microscopy, near-infrared imaging or optical tomography (NIRI/NIROT), quantum key distribution (QKD), quantum random number generators (QRNG), quantum cryptography, etc.


Single-photon avalanche diodes (SPAD) fabricated in standard CMOS technology have been receiving a great amount of attention from both scientific and industrial communities as a key technology for those applications described above, because they can provide single-photon detection and photon-counting capability together with very useful functionalities such as photon time-of-flight evaluation and histogram processing, based on the digital nature of their output, extremely high gain from the Geiger-mode operation, and integrated CMOS circuitry, as well as the most cost-effective, high-volume solution.


Recently, more and more advanced CMOS technologies have become available for the fabrication of SPADs, including technology nodes smaller than 65 nm, CMOS image sensor (CIS) processes, processes providing image sensor and/or SPAD dedicated layers, as well as 3D-stacking technologies. The latter in particular are attracting significant attention because they hold the promise for better sensitivity and more functionality per pixel. This talk will cover fundamentals of the CMOS-SPADs, applications based on the sensors, and cutting-edge technologies. A brief outlook on the future of these sensors will conclude the talk.
