Title New generation of superconducting nanowire single-photon detectors Type Conference Article
Year 2015 Publication EPJ Web of Conferences Abbreviated Journal EPJ Web of Conferences
Volume 103 Issue Pages 01006 (1 to 2)
Keywords SSPD, SNSPD
Abstract We present an overview of recent results for new generation of infrared and optical superconducting nanowire single-photon detectors (SNSPDs) that has already demonstrated a performance that makes them devices-of-choice for many applications. SNSPDs provide high efficiency for detecting individual photons while keeping dark counts and timing jitter minimal. Besides superior detection performance over a broad optical bandwidth, SNSPDs are also compatible with an integrated optical platform as a crucial requirement for applications in emerging quantum photonic technologies. By embedding SNSPDs in nanophotonic circuits we realize waveguide integrated single photon detectors which unite all desirable detector properties in a single device.

Title Towards local oscillators based on arrays of niobium Josephson junctions Type Journal Article
Year 2015 Publication Supercond. Sci. Technol. Abbreviated Journal Supercond. Sci. Technol.
Volume 28 Issue 5 Pages 055002 (1 to 7)
Keywords Josephson junction local oscillators, JJ LO
Abstract Various applications in the field of terahertz technology are in urgent need of compact, wide-tunable solid-state continuous wave radiation sources with a moderate power. However, satisfactory solutions for the THz frequency range are scarce yet. Here we report on coherent radiation from a large planar array of Josephson junctions (JJs) in the frequency range between 0.1 and 0.3 THz. The external resonator providing the synchronization of JJ array is identified as a straight fragment of a single-strip-line containing the junctions themselves. We demonstrate a prototype of the quasioptical heterodyne receiver with the JJ array as a local oscillator and a hot-electron bolometer mixer.

Title Photonic integrated circuits for Department of Defense-relevant chemical and biological sensing applications: state-of-the-art and future outlooks Type Conference Article
Year 2019 Publication Opt. Eng. Abbreviated Journal Opt. Eng.
Volume 58 Issue 02 Pages 1
Keywords photonic integrated circuits, PIC, optical waveguides, defense applications
Abstract Photonic integrated circuits (PICs), the optical counterpart of traditional electronic integrated circuits, are paving the way toward truly portable and highly accurate biochemical sensors for Department of Defense (DoD)-relevant applications. We introduce the fundamentals of PIC-based biochemical sensing and describe common PIC sensor architectures developed to-date for single-identification and spectroscopic sensor classes. We discuss DoD investments in PIC research and summarize current challenges. We also provide future research directions likely required to realize widespread application of PIC-based biochemical sensors. These research directions include materials research to optimize sensor components for multiplexed sensing; engineering improvements to enhance the practicality of PIC-based devices for field use; and the use of synthetic biology techniques to design new selective receptors for chemical and biological agents.

Title Effect of the wire width on the intrinsic detection efficiency of superconducting-nanowire single-photon detectors Type Journal Article
Year 2014 Publication J. Appl. Phys. Abbreviated Journal J. Appl. Phys.
Volume 116 Issue 4 Pages 043906 (1 to 9)
Keywords NbN SSPD, SNSPD, TaN
Abstract A thorough spectral study of the intrinsic single-photon detection efficiency in superconducting TaN and NbN nanowires with different widths has been performed. The experiment shows that the cut-off of the intrinsic detection efficiency at near-infrared wavelengths is most likely controlled by the local suppression of the barrier for vortex nucleation around the absorption site. Beyond the cut-off quasi-particle diffusion in combination with spontaneous, thermally activated vortex crossing explains the detection process. For both materials, the reciprocal cut-off wavelength scales linearly with the wire width where the scaling factor agrees with the hot-spot detection model.
