Swabian Instruments together with Université de Sherbrooke demonstrated a record-breaking low timing jitter with room-temperature single photon detectors. The measured TCSPC correlation of a full two photon coincidence with two Sherbrooke’s single photon detector module and a pre-release unit of the new Swabian Instruments Time Tagger Ultra HiRes results in a total jitter of 20.3 ps FWHM. This corresponds to a 12.5 ps FWHM single photon timing resolution for the single SPAD detectors.
