摘要： The present invention relates to a symmetric absorber-coupled far-infrared microwave kinetic inductance detector including: a membrane having an absorber disposed thereon in a symmetric cross bar pattern; and a microstrip including a plurality of conductor microstrip lines disposed along all edges of the membrane, and separated from a ground plane by the membrane. The conducting microstrip lines are made from niobium, and the pattern is made from a superconducting material with a transition temperature below niobium, including one of aluminum, titanium nitride, or molybdenum nitride. The pattern is disposed on both a top and a bottom of the membrane, and creates a parallel-plate coupled transmission line on the membrane that acts as a half-wavelength resonator at readout frequencies. The parallel-plate coupled transmission line and the conductor microstrip lines form a stepped impedance resonator. The pattern provides identical power absorption for both horizontal and vertical polarization signals.

摘要： A method and a device for reducing the extrinsic dark count of a superconducting nanowire single photon detector (SNSPD), it comprises the steps of: integrating a multi-layer film filter on the superconducting nanowire single photon detector; the multi-layer film filter is a device implemented by a multi-layer dielectric film and having a band-pass filtering function. The extrinsic dark count is the dark count triggered by optical fiber blackbody radiance and external stray light. The superconducting nanowire single photon detector comprises: a substrate having an upper surface integrated with an upper anti-reflection layer and a lower surface integrated with a lower anti-reflection layer; an optical cavity structure; a superconducting nanowire; and a reflector. The present invention is easy to operate, and only needs to integrate the multi-layer film filter on the substrate of the SNSPD to filter non-signal radiation.

摘要： A radiation detecting array 10 has a frequency domain architecture wherein incident radiation is imaged in parallel by an array of radiation detectors 12-16. Each radiation detector has an associated amplitude to frequency conversion device 18-22 for providing output signals wherein the output of each photodetector is represented as a frequency within a uniquely identified band of frequencies, the specific frequency being a function of the output signal amplitude of the photodetector. The readout of one or more selected detectors is accomplished by providing a swept frequency band or bands associated with the desired detector or detectors and mixing the detector frequencies with the swept band. The frequency representing the photodetector output may be input directly to a low dispersion transmission line 30. The unit cells may include radiation detectors comprised of superconducting material and also superconducting components that inherently manifest current or voltage to frequency conversion characteristics in accordance with the Josepson effect. An array having high temperature superconducting components includes photodetectors 60, associated voltage to frequency convertors 64 and a transmission line 70 integrated upon a common substrate.

摘要： An omnidirectional measurement system for a time-varying characteristic of atmospheric vapor radiation includes an antenna and calibrator assembly, a receiver assembly, a room temperature IF assembly, and a data acquisition and system control assembly. Atmospheric vapor features a wide profile and strong radiation in a frequency band of 183 GHz, and is often seen in the characteristic measurement of atmospheric vapor in high-altitude areas. The omnidirectional measurement system combines a superconductor-insulator-superconductor (SIS) mixer with high detection sensitivity in the frequency band of 183 GHz with a structure that integrates pitch scanning, omnidirectional scanning, and automatic calibration to achieve fast and high-precision omnidirectional scanning measurement of the time-varying characteristic of atmospheric vapor radiation. The omnidirectional measurement system has a pitch adjustment-based fast omnidirectional scanning function, and can measure the time-varying characteristic of atmospheric vapor radiation with higher precision and higher temporal resolution through the SIS mixer with higher sensitivity.
