SUPERCONDUCTING NANOWIRE AVALANCHE PHOTODETECTORS WITH REDUCED CURRENT CROWDING

Superconducting nanowire avalanche photodetectors (SNAPs) have using meandering nanowires to detect incident photons. When a superconducting nanowire absorbs a photon, it switches from a superconducting state to a resistive state, producing a change in voltage that can be measured across the nanowire. A SNAP may include multiple nanowires in order to increase the fill factor of the SNAP's active area and the SNAP's detection efficiency. But using multiple meandering nanowires to achieve high fill-factor in SNAPs can lead to current crowding at bends in the nanowires. This current crowding degrades SNAP performance by decreasing the switching current, which the current at which the nanowire transitions from a superconducting state to a resistive state. Fortunately, staggering the bends in the nanowires reduces current crowding, increasing the nanowire switching current, which in turn increases the SNAP dynamic range.
