Abstract |
We describe a novel method of operation of the HEB direct detector for use with a Fourier Transform Spectrometer. Instead of elevating the bath temperature, we have measured the RF response of waveguide HEB mixers by applying microwave radiation to select appropriate bias conditions. In our experiment, a microwave signal is injected into the HEB mixer via its IF port. By choosing an appropriate injection level, the device can be operated close to the desired operating point. Furthermore, we have shown that both thermal biasing and microwave injection can reproduce the same spectral response of the HEB mixer. However, with the use of microwave injection, there is no need to wait for the mixer to reach thermal equilibrium, so characterisation can be done in less time. Also, the liquid helium consumption for our wet cryostat is also reduced. We have demonstrated that the signal- to-noise ratio of the FTS measurements can be improved with microwave injection. |

Abstract |
A calculation error was made in the original publication of this letter. The error was in the calculation of the noise equivalent power (NEP) values for the avalanche photodiode detector (APD) and the superconducting single photon detector (SSPD), the incorrect values were plotted on the right axis in Fig. 1(b). The correct NEP values were calculated with the same equation reported in the original letter and the revised Fig. 1(b) is shown below. The other conclusions of the paper remain unaltered. |

Abstract |
Мы представляем быстродействующий сверхпроводниковый однофотонный детектор (SSPD) для дальнего инфракрасного диапазона на основе ультратонкой монокристаллической пленки NbN толщиной 3 нм, состоящий из параллельных полосок. QE на длине волны 1,5.μм и 1,3 μм для предложенного SSPD практически одинаковы. SSPD показывает отклик длительностью 200 пс, что открывает путь к детекторам, обладающим скоростью счета свыше 1 ГГц. |
