Abstract
Voxtel proposes to develop fiber-coupled near-infrared avalanche photodiode (APD) receivers with photon detection efficiency (PDE) and dark count rate (DCR) with more than two orders of magnitude faster maximum count rate (MCR) than Geiger-mode APDs, which are constrained by a fundamental tradeoff between DCR and MCR: if the APD is cooled to reduce DCR, then its dead time must increase to avoid afterpulsing, which reduces MCR.
