Abstract
- We have realized superconducting single photon detectors with reduced inductance and increased signal pulse amplitude. The detectors are based on a parallel connection of ultrathin NbN nanowires with a common bias inductance. When properly biased, an absorbed photon induces a cascade switch of all the parallel wires generating a signal pulse amplitude of 2 mV. The parallel wire configuration lowers the detector inductance and reduces the response time well below 1 ns. [ABSTRACT FROM AUTHOR]
