A CMOS SPAD-based QVGA image sensor with 8µm pixel pitch and 26.8% fill factor is presented. The combination of analogue pixel electronics and scalable sharedwell SPAD devices facilitate high resolution, high fill-factor SPAD imaging arrays exhibiting photon shot noise limited statistics. The SPAD has 47CPS dark count rate at 1.5V excess bias (EB), 39.5% photon detection probability at 480nm and minimum 1.1ns dead time at 1V EB. Analogue single photon counting imaging is demonstrated with maximum 14.2mV/SPAD event sensitivity and 0.06e-minimum equivalent read noise. Binary Quanta Image Sensor (QIS) 16kFPS real-time oversampling is shown, verifying single photon QIS theory with 4.6x over-exposure latitude and 0.168e-read noise.

“…Finally, in the near future SPAD-based imagers could definetely take advantage of the advent of 3D-stacked fabrication technologies exploiting the co-integration of specialized CIS back-side illuminated sensing layer with deep-submicron digital CMOS. BSI-compatible SPADs offer higher sensitivity in the NIR region that combined with the stacking on advanced digital CMOS technologies will enable the realisation of pixel pitches in the order of a few micrometers and high fill factor [ 40 , 41 ]. At the same time efficient processing of the generated data flow will still be possible.…”

This paper reviews the state of the art of single-photon avalanche diode (SPAD) image sensors for time-resolved imaging. The focus of the paper is on pixel architectures featuring small pixel size (<25 μm) and high fill factor (>20%) as a key enabling technology for the successful implementation of high spatial resolution SPAD-based image sensors. A summary of the main CMOS SPAD implementations, their characteristics and integration challenges, is provided from the perspective of targeting large pixel arrays, where one of the key drivers is the spatial uniformity. The main analog techniques aimed at time-gated photon counting and photon timestamping suitable for compact and low-power pixels are critically discussed. The main features of these solutions are the adoption of analog counting techniques and time-to-analog conversion, in NMOS-only pixels. Reliable quantum-limited single-photon counting, self-referenced analog-to-digital conversion, time gating down to 0.75 ns and timestamping with 368 ps jitter are achieved.

“…For the detector used here we estimated the photon detection efficiency (PDE), by comparison with an independent EMCCD measurement, to be 42% at 515 nm and 7 V excess bias. While PDE, DCR, dynamic range and afterpulsing are often depicted in the literature, only few works discuss the issue of inter-pixel crosstalk [6,20,28,44,60]. While both afterpulsing and crosstalk generate artificial correlations, afterpulsing artifacts are avoided here altogether by disregarding the autocorrelation of any single detector, as typically done in HBT experiments.…”

Temporal photon correlation measurement, instrumental to probing the quantum properties of light, typically requires multiple single photon detectors. Progress in single photon avalanche diode (SPAD) array technology highlights their potential as high performance detector arrays for quantum imaging and photon number resolving (PNR) experiments. Here, we demonstrate this potential by incorporating a novel on-chip SPAD array with 55% peak photon detection probability, low dark count rate and crosstalk probability of 0.14% per detection, in a confocal microscope. This enables reliable measurements of second and third order photon correlations from a single quantum dot emitter. Our analysis overcomes the inter-detector optical crosstalk background even though it is over an order of magnitude larger than our faint signal. To showcase the vast application space of such an approach, we implement a recently introduced super-resolution imaging method, quantum image scanning microscopy (Q-ISM).
