Sub-10 ps monolithic and low-power photodetector readout

Abstract Recent advances in photon detectors have resulted in high-density imaging arrays that offer many performance and cost advantages. In particular, the excellent transit-time-spread of certain devices show promise to provide tangible benefits in applications such as positron emission tomography (PET). Meanwhile, high-density, high-performance readout techniques have not kept on pace for exploiting these developments. Photodetector readout for next generation high event rate particle identification and time-resolved PET requires a highly integrated, low-power, and cost-effective readout technique. We propose fast waveform sampling as a method that meets these criteria and demonstrate that sub-10 ps resolution can be obtained for an existing device.
