Title Single-pixel camera with a large-area microstrip superconducting single photon detector on a multimode fiber Type Journal Article
Year 2021 Publication Appl. Phys. Lett. Abbreviated Journal Appl. Phys. Lett.
Volume 118 Issue 18 Pages 181103
Keywords NbN SSPD, SNSPD
Abstract (down) High sensitivity imaging at the level of single photons is an invaluable tool in many areas, ranging from microscopy to astronomy. However, development of single-photon sensitive detectors with high spatial resolution is very non-trivial. Here we employ the single-pixel imaging approach and demonstrate a proof-of-principle single-pixel single-photon imaging setup. We overcome the problem of low light gathering efficiency by developing a large-area microstrip superconducting single photon detector coupled to a multi-mode optical fiber interface. We show that the setup operates well in the visible and near infrared spectrum, and is able to capture images at the single-photon level.

Title Dual origin of room temperature sub-terahertz photoresponse in graphene field effect transistors Type Journal Article
Year 2018 Publication Appl. Phys. Lett. Abbreviated Journal Appl. Phys. Lett.
Volume 112 Issue 14 Pages 141101 (1 to 5)
Keywords graphene field effect transistors, FET
Abstract (down) Graphene is considered as a promising platform for detectors of high-frequency radiation up to the terahertz (THz) range due to its superior electron mobility. Previously, it has been shown that graphene field effect transistors (FETs) exhibit room temperature broadband photoresponse to incoming THz radiation, thanks to the thermoelectric and/or plasma wave rectification. Both effects exhibit similar functional dependences on the gate voltage, and therefore, it was difficult to disentangle these contributions in previous studies. In this letter, we report on combined experimental and theoretical studies of sub-THz response in graphene field-effect transistors analyzed at different temperatures. This temperature-dependent study allowed us to reveal the role of the photo-thermoelectric effect, p-n junction rectification, and plasmonic rectification in the sub-THz photoresponse of graphene FETs.

Title Far-ir heterodyne radiometric measurements with quasioptical Schottky diode mixers Type Journal Article
Year 1978 Publication Appl. Phys. Lett. Abbreviated Journal Appl. Phys. Lett.
Volume 33 Issue 2 Pages 151-154
Keywords Schottky
Abstract (down) Frequency countings close to a phase locked zone in an electronic receiver show a 1/f power spectral density. The noise scaling versus the frequency deviation and the open loop gain are found from Adler's model of the phase locked loop. This fully agrees with experiments performed at 5 MHz on a receiver with a Schottky diode mixer and a low pass filter. The 1/f amplitude and frequency noise due to the whole set of (sub)harmonics is explained from a nonlinear mapping, with a coupling coefficient related to the structure of prime numbers.

Title Time-resolved spectroscopy of InAsP/InP(001) quantum dots emitting near 2 μm Type Journal Article
Year 2010 Publication Appl. Phys. Lett. Abbreviated Journal Appl. Phys. Lett.
Volume 97 Issue 13 Pages 131907 (1 to 3)
Keywords SSPD, SNSPD, InAsP/InP quantum dots
Abstract (down) By using superconducting single photon detectors, we perform time-resolved characterization of a small ensemble of InAsP/InP quantum dots grown by metal organic vapor phase epitaxy, emitting at wavelengths between 1.6 and 2.2 μm. We demonstrate that alloying phosphorus with InAs allows to shift the emission wavelength toward higher wavelengths, while keeping the high optical quality of these quantum dots at room temperature, with no decrease in their radiative lifetime.

Title An ultra-fast superconducting Nb nanowire single-photon detector for soft x-rays Type Journal Article
Year 2012 Publication Abbreviated Journal Appl. Phys. Lett.
Volume 101 Issue Pages
Keywords SSPD, SNSPD, x-ray, Nb
Abstract (down) Although superconducting nanowire single-photon detectors (SNSPDs) are well studied regarding the

detection of infrared/optical photons and keV-molecules, no studies on continuous x-ray photon

counting by thick-film detectors have been reported so far. We fabricated a 100 nm thick niobium

x-ray SNSPD (an X-SNSPD) and studied its detection capability of photons with keV-energies in

continuous mode. The detector is capable to detect photons even at reduced bias currents of 0.4%,

which is in sharp contrast to optical thin-film SNSPDs. No dark counts were recorded in extended

measurement periods. Strikingly, the signal amplitude distribution depends significantly on the photon

energy spectrum.VC
