  Title Hot electron bolometric mixers: new terahertz technology Type Journal Article
  Year 1999 Publication Infrared Physics & Technology Abbreviated Journal Infrared Physics & Technology  
  Volume 40 Issue 3 Pages 199-206  
  Keywords NbN HEB mixers  
  Abstract This paper presents an overview of recent results for NbN phonon-cooled hot electron bolometric (HEB) mixers. The noise temperature of the receivers based on both quasioptical and waveguide versions of HEB mixers has crossed the level of 1 K GHz−1 at 430 GHz (410 K), 600–650 GHz (480 K), 750 GHz (600 K), 810 GHz (780 K) and is close to that level at 1.1 THz (1250 K) and 2.5 THz (4500 K). The gain bandwidth measured for quasioptical HEB mixer at 620 GHz reached 4 GHz and the noise temperature bandwidth was almost 8 GHz. Local oscillator power requirements are about 1 μW for mixers made by photolithography and about 100 nW for mixers made by e-beam lithography. A waveguide version of 800 GHz receiver was installed at the Submillimeter Telescope Observatory on Mt. Graham, AZ, to conduct astronomical observations of known submillimeter lines (CO, J=7→6, CI, J=2→1). It was proved that the receiver works as a practical instrument.

  Title Terahertz superconducting hot-electron bolometer mixers and their application in radio astronomy Type Journal Article
  Year 2003 Publication Radiophys. Quant. Electron. Abbreviated Journal  
  Volume 46 Issue 8/9 Pages 604-617  
  Keywords NbN HEB mixers  
  Abstract We review the latest developments, research, and radioastronomy applications of hot-electron bolometer (HEB) mixers operated in the terahertz waveband. The physical principles of operation of terahertz HEB mixers are presented, their manufacturing from ultrathin NbN films, the main HEB-mixer parameters and their measurement techniques are discussed, and practical terahertz radioastronomy projects based on heterodyne receivers with HEB mixers are considered.

  Title High resolution THz gas spectrometer based on semiconductor and superconductor devices Type Conference Article
  Year 2017 Publication EPJ Web Conf. Abbreviated Journal EPJ Web Conf.  
  Volume 132 Issue Pages 02001 (1 to 2)  
  Keywords NbN HEB mixers, detectors, THz spectroscopy  
  Abstract The high resolution THz gas spectrometer consists of a synthesizer based on Gunn generator with a semiconductor superlattice frequency multiplier as a radiation source, and an NbN hot electron bolometer in a direct detection mode as a THz radiation receiver was presented. The possibility of application of a quantum cascade laser as a local oscillator for a heterodyne receiver which is based on an NbN hot electron bolometer mixer is shown. The ways for further developing of the THz spectroscopy were outlined.

  Title Heterodyne detection of THz radiation with a superconducting hot‐electron bolometer mixer Type Journal Article
  Year 1996 Publication Appl. Phys. Lett. Abbreviated Journal Appl. Phys. Lett.  
  Volume 69 Issue 2 Pages 260-262  
  Keywords NbN HEB mixers  
  Abstract We report on the use of a superconducting hot‐electron bolometer mixer for heterodyne detection of terahertz radiation. Radiation with a wavelength of 119 μm was coupled to the mixer, a NbN microbridge, by a hybrid quasioptical antenna consisting of an extended hyperhemispherical lens and a planar logarithmic spiral antenna. We found, at an intermediate frequency of 1.5 GHz, a system double side band noise temperature of ≊40 000 K and conversion losses of 25 dB. We also discuss the possibilities of further improvement of the mixer performance.

  Title Low noise NbN lattice-cooled superconducting hot-electron bolometric mixers at submillimeter wavelengths Type Journal Article
  Year 1997 Publication Appl. Phys. Lett. Abbreviated Journal Appl. Phys. Lett.  
  Volume 70 Issue 12 Pages 1619-1621  
  Keywords NbN HEB mixers  
  Abstract Lattice-cooled superconducting hot-electron bolometric mixers are used in a submillimeter-wave waveguide heterodyne receiver. The mixer elements are niobium nitride film with 3.5 nm thickness and ∼10 μm2 area. The local oscillator power for optimal performance is estimated to be 0.5 μW, and the instantaneous bandwidth is 2.2 GHz. At an intermediate frequency centered at 1.4 GHz with 200 MHz bandwidth, the double sideband receiver noise temperature is 410 K at 430 GHz. The receiver has been used to detect molecular line emission in a laboratory gas cell.
