In our new paper, to appear in the IEEE Jornal of Selected Topics in Quantum Electronics (JSTQE), we have demonstrated fully-saturated nanowire single-photon detectors with 24 ps jitter. Furthermore we show an improved fabrication process that allowed us to increase the fabrication yield of our detectors.
