  Title Superconducting hot electron bolometer mixer for middle IR range Type Conference Article
  Year 2006 Publication Proc. 16th Int. Crimean Microwave and Telecommunication Technology Abbreviated Journal Proc. 16th Int. Crimean Microwave and Telecommunication Technology  
  Volume 2 Issue Pages 686-687  
  Keywords IR NbN HEB mixer, detector, GaAs substrate  
  Abstract The developed directly lens coupled hot electron bolometer (HEB) mixer was based on 5 nm superconducting NbN deposited on GaAs substrate. The layout of the structure, including 30x20 mcm^2 active area coupled with a 50 Ohm coplanar line, was patterned by photolithography. The responsivity of the mixer was measured in a direct detection mode in the 25-64 THz frequency range. The noise performance of the mixer and the directivity of the receiver were investigated in a heterodyne mode. A 10.6 mum wavelength CW CO2 laser was utilized as a local oscillator.

  Volume 2 Issue Pages 684-685  
  Keywords NbN SSPD, SNSPD  
  Abstract Presented in this paper are the results of research of NbN-film superconducting single-photon detector. At 2 K temperature, quantum efficiency in the visible light (0.56 mum) reaches 30-40 %. With the wavelength increase quantum efficiency decreases and comes to  20% at 1.55 mum and  0.02% at 5.6 mum. Minimum dark counts rate is 2times10-4s-1. The jitter of detector is 35 ps. The detector was successfully implemented for integrated circuits non-invasive optical testing. It is also perspective for quantum cryptography systems

  Title Effect of microwave radiation on the stability of terahertz hot-electron bolometer mixers Type Conference Article
  Year 2006 Publication Proc. SPIE Abbreviated Journal Proc. SPIE  
  Volume 6373 Issue Pages 63730J (1 to 5)  
  Keywords NbN HEB mixers, hot-electron bolometer mixers, stability, Allan variance, LO power fluctuations  
  Abstract We report our studies of the effect of microwave radiation, with a frequency much lower than that corresponding to the energy gap of the superconductor, on the performance of the NbN hot-electron bolometer (HEB) mixer incorporated into a THz heterodyne receiver. It is shown that exposing the HEB mixer to microwave radiation does not result in a significant rise of the receiver noise temperature and degradation of the mixer conversion gain so long as the level of microwave power is small compared to the local oscillator drive. Hence the injection of a small, but controlled amount of microwave radiation enables active compensation of local oscillator power and coupling fluctuations which can significantly degrade the stability of HEB mixer receivers.

  Title Nanowire Single-photon detector with an integrated optical cavity and anti-reflection coating Type Journal Article
  Year 2006 Publication Opt. Express Abbreviated Journal Opt. Express  
  Volume 14 Issue 2 Pages 527-534  
  Keywords SSPD, SNSPD, cavity  
  Abstract We have fabricated and tested superconducting single-photon detectors and demonstrated detection efficiencies of 57% at 1550-nm wavelength and 67% at 1064 nm. In addition to the peak detection efficiency, a median detection efficiency of 47.7% was measured over 132 devices at 1550 nm. These measurements were made at 1.8K, with each device biased to 97.5% of its critical current. The high detection efficiencies resulted from the addition of an optical cavity and anti-reflection coating to a nanowire photodetector, creating an integrated nanoelectrophotonic device with enhanced performance relative to the original device. Here, the testing apparatus and the fabrication process are presented. The detection efficiency of devices before and after the addition of optical elements is also reported.
