Performances of NbTiN superconducting nanowire single photon detector
We present high performance fiber-coupled niobium titanium nitride superconducting nanowire single photon detectors fabricated on thermally oxidized silicon substrates. By applying a double sided cavity structure, simulated absorptance in the nanowire meander reached 97% at 1550 nm wavelength. The fabricated device showed a system detection efficiency (DE) of 74% at 1550 nm, dark count rate of 100 c/s, and a full width at half maximum timing jitter of 68 ps under a bias current of 18.0 μA with a practical Gifford-McMahon cryocooler system.
