Advances in time-of-flight and time-correlated single-photon-counting devices (original) (raw)

Advancements in the design and production of single-photon avalanche diodes (SPADs) have led to significant improvements in time-of-flight and time-correlated single-photon counting applications. Utilizing a cost-effective 0.35 m CMOS technology, this work introduces innovative SPAD arrays that feature enhanced temporal and spatial resolutions, greater photon-detection efficiency across a wide wavelength range, and reduced noise levels. Key developments include a novel p-n junction structure that operates effectively under controlled conditions, achieving remarkable performance in 3D imaging and low-light security applications.
