  Title A low temperature bolometer heterodyne receiver for Millimeter wave astronomy Type Journal Article
  Year (up) 1973 Publication Rev. Sci. Instrum. Abbreviated Journal Rev. Sci. Instrum.  
  Volume 44 Issue 8 Pages 1009-1014  
  Keywords InSb HEB mixer  
  Abstract Liquid helium cooled InSb hot electronbolometers are used in a balanced mixer configuration as detectors for an imagelessmicrowave receiver. The system is designed for mounting at the prime focus of the National Radio Astronomy Observatory (NRAO) 11 m antenna at Kitt Peak, Arizona, and is suitable for the study of rotational line spectra of interstellar gas molecules. Currently the operating frequency is in the 90–140 GHz band where the double sideband system noise temperature is 250 K.

  Title Electromagnetic radiation mixer based on electron heating in resistive state of superconductive Nb and YBaCuO films Type Journal Article
  Year (up) 1991 Publication IEEE Trans. Magn. Abbreviated Journal IEEE Trans. Magn.  
  Volume 27 Issue 2 Pages 1317-1320  
  Keywords YBCO, HTS, Nb HEB mixers  
  Abstract A theory of an electron-heating mixer which makes it possible to calculate all the characteristics of the device is developed. It is shown that positive conversion gain is possible for such a mixer in the millimeter to near-infrared wavelength range. The dynamic range and the optimum heterodyne power can be selected from a very wide interval by varying the mixing element volume. Measurements made for Nb within the frequency range of 120-750 GHz confirm the theory. The conversion loss obtained at T=1.6 K and normalized to the element reaches 0.3 dB in the intermediate frequency band of 40 MHz; the possible noise temperature is 50 K. The estimation of noise temperature and output band for YBaCuO at T=77 yields 200 K and more than 10 GHz, respectively.

  Title Hot electron mixers, the potential competition Type Conference Article
  Year (up) 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.

  Title Mixers using superconducting Nb films in the resistive state Type Conference Article
  Year (up) 1993 Publication 23rd European Microwave Conf. Abbreviated Journal 23rd European Microwave Conf.  
  Volume Issue Pages 787-789  
  Keywords Nb HEB mixers  
  Abstract The mixing of 20 GHz radiation in a Nb superconducting film in the resistive state was studied. The experiment gave evidence of electron-heating to be the origin of the non-linear phenomenon. The requirements on the operation mode and on the film parameters in order to obtain small conversion losses or even gain are determined. Our measurements indicate a conversion loss of about 6-8 dB. The hot-electron bolometer is considered to be very promising for use in heterodyne receivers in a wide frequency range from microwaves to terahertz frequencies.

  Title Optical mixing in a patterned YBa2Cu3O7-δ thin film Type Journal Article
  Year (up) 1994 Publication Appl. Phys. Lett. Abbreviated Journal Appl. Phys. Lett.  
  Volume 65 Issue 26 Pages 3398-3400  
  Keywords YBCO HTS HEB mixer, bandwidth  
  Abstract Mixing of 1.56 µm infrared radiation from two lasers in a high quality YBa2Cu3O7-δ thin film, patterned to parallel strips, was demonstrated. A mixer bandwidth of 18 GHz, limited by the measurement system, was obtained. A model based on nonequilibrium electron heating gives a good fit to the data and predicts an intrinsic mixer bandwidth in excess of 100 GHz, operating in the whole infrared spectrum. Reduction of bolometric effects and ways to decrease the conversion loss of the mixer is discussed. The minimum conversion loss is expected to be ~10 dB.

  Title Terahertz technology in Russia Type Conference Article
  Year (up) 1994 Publication 24th European Microwave Conf. Abbreviated Journal 24th European Microwave Conf.  
  Volume 1 Issue Pages 113-121  
  Keywords BWO, HEB mixers  
  Abstract The presentation consider the parameters and operating peculiarities of unique microwave generators of the terahertz range which have been created in Russia – the backward wave oscillators – as well as certain devices based on these generators, such as high resolution. spectrometers and time-resolving spectrometers with picosecond temporal resolution. Most resent BWO-based studies are illustrated by a project devoted to superconductive hot-electron. bolometers which are of great independent value for the terahertz technology as high-sensitive picosecond detectors and low noise broad-band mixers.

  Title Picosecond detection and broadband mixing of near-infrared radiation by YBaCuO films Type Conference Article
  Year (up) 1994 Publication Proc. SPIE Abbreviated Journal Proc. SPIE  
  Volume 2159 Issue Pages 68-76  
  Keywords YBCO HTS HEB mixer  
  Abstract Nonequilibrium picosecond and bolometric responses of YBCO films 500 angstroms thick patterned into 20 X 20 micrometers 2 size structure to 17 ps laser pulses and modulated radiation of GaAs and CO2 lasers have been studied. The modulation frequencies up to 10 GHz for GaAs laser and up to 1 GHz for CO2 were attained. The use of small radiation power (1 – 10 mW/cm2 for cw radiation and 10 – 100 nJ/cm2 for pulse radiation) in combination with high sensitive read-out system made possible to avoid any non-linear transient processes caused by an overheating of sample above a critical temperature or S-N switching enhanced by an intense radiation. Responses due to the change of kinetic inductance were believed to be negligible. The only signals observed were caused by a small change of the film resistance either in the resistive state created by a bias current or in the normal state. The data obtained by means of pulse and modulation techniques are in agreement. The responsivity about 1 V/W was measured at 1 GHz modulation frequency both for 0.85 micrometers and 10.6 micrometers wavelengths. The sensitivity of high-Tc fast wideband infrared detector is discussed.
