Abstract
By using 0.25 μm high-voltage CMOS technology, we have designed and fabricated a structure of single-photon detectors. The new single-photon avalanche diode (SPAD) has (to our knowledge) the lowest dark count rate per unit area at room temperature without any technology customization. Our design is promising for realizing low-cost and high-performance SPAD arrays for imaging applications.
