- W1985392743 abstract "Superconducting single-photon detector (SSPD) is patterned from 4-nm-thick NbN film deposited on sapphiresubstrate as a 100-nm-wide strip. Due to its high detection efficiency, low dark counts, and picosecond timingjitter SSPD has become a competitor to the InGaAs avalanche photodiodes at 1550 nm and longer wavelengths.Although the SSPD is operated at liquid helium temperature its efficient single-mode fibre coupling enabled itsusage in many applications ranging from single-photon sources research to quantum cryptography. In our striveto increase the detection efficiency at 1550 nm and longer wavelengths we developed and fabricated SSPD withthe strip almost twice narrower compared to the standard 100 nm. To increase the voltage response of the devicewe utilized cascade switching mechanism: we connected 50-nm-wide and 10-μm-long strips in parallel coveringthe area of 10 μmx10 μm. Absorption of a photon breaks the superconductivity in a strip leading to the biascurrent redistribution between other strips followed their cascade switching. As the total current of all the stripsabout is 1 mA by the order of magnitude the response voltage of such an SSPD is several times higher comparedto the traditional meander-shaped SSPDs. In middle infrared (about 3 μm wavelength) these devices have thedetection efficiency several times higher compared to the traditional SSPDs." @default.
