  Title Stabilization scheme for hot-electron bolometer receivers using microwave radiation Type Journal Article
  Year 2009 Publication IEEE Trans. Appl. Supercond. Abbreviated Journal IEEE Trans. Appl. Supercond.  
  Volume 19 Issue 1 Pages 14-19  
  Keywords HEB, mixer, Allan variance, stabilization, radiometer equation  
  Abstract We present the results of a stabilization scheme for terahertz receivers based on NbN hot-electron bolometer (HEB) mixers that uses microwave radiation with a frequency much lower than the gap frequency of NbN to compensate for mixer current fluctuations. A feedback control loop, which actively controls the power level of the injected microwave radiation, has successfully been implemented to stabilize the operating point of the HEB mixer. This allows us to increase the receiver Allan time to 10 s and also improve the temperature resolution of the receiver by about 30% in the total power mode of operation.

  Title Infrared and terahertz detectors on basis of superconducting nanostructures Type Conference Article
  Year 2010 Publication Microwave and Telecom. Technol. (CriMiCo), 20th Int. Crimean Conf. Abbreviated Journal  
  Volume Issue Pages 823-824  
  Keywords SSPD, SNSPD, HEB  
  Abstract Results of development of single-photon receiving systems of visible, infrared and terahertz range based on thin-film superconducting nanostructures are presented. The receiving systems are produced on the basis of superconducting nanostructures, which function by means of hot-electron phenomena.
