Photon counting in one or in arrays of pixels is useful in a number of applications, from more traditional ones, such as low-light-level and fluorescence imaging, superresolution microscopy, 3D time-of-flight sensing, and NIR optical tomography [1-6], to niche applications, such ...
In this paper, a novel CMOS single-photon avalanche diode (SPAD) is presented, and the device is designed using a vertical p-i-n diode construction. The p-i-n diode with a wide depletion region enables a low-noise operation. The proposed design achieves dark count rates of 1.5 cp ...
