  Title Coherent detection of weak signals with superconducting nanowire single photon detector at the telecommunication wavelength Type Conference Article
  Year 2017 Publication Proc. SPIE Abbreviated Journal Proc. SPIE  
  Volume 10229 Issue Pages 0G (1 to 12)  
  Keywords SSPD mixer, SNSPD, coherent detection, weak signal detection, superconducting nanostructures  
  Abstract Achievement of the ultimate sensitivity along with a high spectral resolution is one of the frequently addressed problems, as the complication of the applied and fundamental scientific tasks being explored is growing up gradually. In our work, we have investigated performance of a superconducting nanowire photon-counting detector operating in the coherent mode for detection of weak signals at the telecommunication wavelength. Quantum-noise limited sensitivity of the detector was ensured by the nature of the photon-counting detection and restricted by the quantum efficiency of the detector only. Spectral resolution given by the heterodyne technique and was defined by the linewidth and stability of the Local Oscillator (LO). Response bandwidth was found to coincide with the detector’s pulse width, which, in turn, could be controlled by the nanowire length. In addition, the system noise bandwidth was shown to be governed by the electronics/lab equipment, and the detector noise bandwidth is predicted to depend on its jitter. As have been demonstrated, a very small amount of the LO power (of the order of a few picowatts down to hundreds of femtowatts) was required for sufficient detection of the test signal, and eventual optimization could lead to further reduction of the LO power required, which would perfectly suit for the foreseen development of receiver matrices and the need for detection of ultra-low signals at a level of less-than-one-photon per second.

  Title Receiver measurements of pHEB beam lead mixers on 3-μm silicon Type Conference Article
  Year 2005 Publication Proc. 30th IRMMW / 13th THz Abbreviated Journal Proc. 30th IRMMW / 13th THz  
  Volume Issue Pages 271-272  
  Keywords  
  Abstract We report on receiver noise measurement results of phonon-cooled HEB beam lead mixers on 3 μm thick silicon. This type of ultra-thin mixer chip with integrated beam leads allows easy assembly into a block and holds great promise for array integration. Receiver measurements from 600-720 GHz are presented with a minimum noise temperature of 500 K at 666 GHz. These results verify the mixer performance of the SOI processing techniques allowing for further design and integration of SOI pHEB mixers in receivers operating above 1 THz.

  Title Quantum key distribution over 300 Type Conference Article
  Year 2014 Publication Proc. SPIE Abbreviated Journal Proc. SPIE  
  Volume 9440 Issue Pages 1F (1 to 9)  
  Keywords SSPD, SNSPD applicatins, quantum key distribution, QKD  
  Abstract We discuss the possibility of polarization state reconstruction and measurement over 302 km by Superconducting Single- Photon Detectors (SSPDs). Because of the excellent characteristics and the possibility to be effectively coupled to singlemode optical fiber many applications of the SSPD have already been reported. The most impressive one is the quantum key distribution (QKD) over 250 km distance. This demonstration shows further possibilities for the improvement of the characteristics of quantum-cryptographic systems such as increasing the bit rate and the quantum channel length, and decreasing the quantum bit error rate (QBER). This improvement is possible because SSPDs have the best characteristics in comparison with other single-photon detectors. We have demonstrated the possibility of polarization state reconstruction and measurement over 302.5 km with superconducting single-photon detectors. The advantage of an autocompensating optical scheme, also known as “plugandplay” for quantum key distribution, is high stability in the presence of distortions along the line. To increase the distance of quantum key distribution with this optical scheme we implement the superconducting single photon detectors (SSPD). At the 5 MHz pulse repetition frequency and the average photon number equal to 0.4 we measured a 33 bit/s quantum key generation for a 101.7 km single mode ber quantum channel. The extremely low SSPD dark count rate allowed us to keep QBER at 1.6% level.

  Title Hot electron mixers, the potential competition Type Conference Article
  Year 1992 Publication Proc. ESA Symp. on Photon Detectors for Space Instrumentation Abbreviated Journal Proc. ESA Symp. on Photon Detectors for Space Instrumentation  
  Volume Issue Pages 201-206  
  Keywords HEB mixers  
  Abstract There is an urgent need in radio astronomy for low noise heterodyne receivers for frequencies above about 500 GHz. It is not certain that mixers based on superconducting quasiparticle tunnelling (SIS mixers) may turn out to be the answer to this need. In order to try to find an alternative way for realizing low noise heterodyne receivers for submillimeter waves, so called hot electron bolometric effects for mixing are now being investigated. Two basically different approaches are tried, one based on semiconductors and one on superconductors. Both methods are briefly discussed in this overview paper.
