Not Accessible

Your library or personal account may give you access

Abstract

We report on a fractal superconducting nanowire avalanche photodetector simultaneously with 60% system efficiency, 1.05 polarization sensitivity, 4-ns recovery time, and 45-ps timing jitter. The efficiency is the highest among polycrystalline SNSPDs with polarization-insensitive designs.
