Unavoidable kinetic inductance of the superconducting nanowire single photon detector results in the signal pulse with a slow falling edge and a large pulse width. It has been a limit for improving the repetition rate for single photon detection. With a snubber made of a coaxial cable terminated with a resistive pot, the original signal pulse can be shaped. A sharp falling edge can be produced with suitable snubber parameters and the final output pulse has a symmetric wave. The pulse width (full width at half maximum) is reduced from 5 to 1 ns.
