(a) Scanning electron micrograph (SEM) of our SSPD device. The meander pattern of -wide nanowire covering area was embedded in a coplanar waveguide structure fabricated from -thick NbN films. Histograms of (b) sheet resistance and (c) of our five (seven) SSPDs with -wide meanders of -thick NbN films on a common MgO substrate.

(a) The phase of as a function of frequency for two devices: -wide nanowire device (total nanowire length was ) and -wide nanowire device (total nanowire length was ). The solid lines are measured data and the dotted lines are curves fitted using the expression of arg . (b) The bias current dependencies of . The and bias current are scaled by and , respectively.
