Description
Summary:In this paper, we present the architecture and the experimental characterization of an improved version of a previously developed 32&#x00A0;&#x00D7;&#x00A0;32 Single Photon Avalanche Diodes (SPADs) and Time to Digital Converters (TDCs) array, and two new arrays (with 8&#x00A0;&#x00D7;&#x00A0;8 and 128&#x00A0;&#x00D7;&#x00A0;1 pixels) with the additional capability of actively gating the detectors with sub-nanosecond rise time. The arrays include high performance SPADs (0.04 cps&#x002F;&#x03BC;m<sup>2</sup>, 50&#x0025; peak PDE) and provide down to 410 ps Full-Width at Half-Maximum (FWHM) single shot precision and excellent linearity. We developed a camera to exploit these imagers in time-resolved, single-photon applications.
