    摘要: Disclosed is a device for reducing the phase noise of a signal (Sin) emitted by a quasi-periodic source having a basic frequency f0. Said device is provided with a superconducting circuit comprising an active line for transmitting voltage pulses by transferring flux quanta F0. Said circuit is defined so as to be provided with a characteristic frequency fc such that 0.3 fc is smaller than or equal to the basic frequency f0 of the quasi-periodic signal (Sin) applied at the input while supplying a voltage pulse signal having the basic frequency f0 at the output.

    摘要: The invention concerns a superconductive electronic component which displays specific properties of an emitter and/or detector for electromagnetic radiation in the submillimetre wave range. The component comprises a planar network of microbridges (webs) formed in a thin layer of a high-temperature superconductor. The latter is grown epitaxially on the substrate with the CuO2 planes either perpendicular or inclined at an angle Υ(1°∫Υ∫89°) to the substrate surface. In this way, each microbridge receives a sequence of stacks of superimposed (intrinsic) Josephson contacts. The invention also concerns superconductive connections (series and parallel) between individual microbridges, whereby switching circuit parameters, such as adaptation of the impedance to the radiation space and maximizing of the radiated output, can be optimized. The frequency and intensity, for example, of the radiation field can be influenced (e.g. modulated) by external means of an electronic control. In particular, this component can continuously cover the frequency range between the far infrared and the microwave range. The invention also concerns some applications of the proposed component, covering both the emission and detection of electromagnetic radiation.

    摘要: An improved oscillating circuit for use in microwave frequency bands has reduced power loss and is made smaller in vertical size. The local oscillating circuit includes an MMIC oscillator which comprises a FET (9), and a resonator (10) connected thereto so as to stabilize the oscillating frequency of the oscillator. The resonator is ring-shaped and arranged as close as several µm to several tens of µm to a predetermined position of a micro strip line forming a feedback loop connected to the FET forming the oscillator. Moreover, the resonator is a thin film formed by depositing a high-temperature superconducting material. As exemplary embodiments, YBCO, niobium and the like, can be used as high-temperature superconducting materials. Furthermore, a portion of the micro strip line, closest to the resonator, is concentrically disposed therewith to form a circular arc portion whose central angle is set at 90 degrees.

    摘要: A digital optical receiver and clock recovery circuit for use in detecting and retiming optical data transmitted at rates up to and exceeding 40 Gb/s. The receiver is made, in part, of superconducting Josephson junctions. The receiver includes an optical signal detector, an SFQ (single flux quantum) transition detector for converting the signal from the photodetector into a stream of single flux quantum signals, and a clock recovery circuit. The clock recovery circuit includes a superconducting ring oscillator in which an SFQ pulse rotates and provides a clock signal at an output of the oscillator. When a pulse from the stream of single flux quantum pulses arrives from the transition detector, two pulses are generated in the ring oscillator. One of the pulses eliminates the rotating SFQ pulse and the second pulse replaces the rotating SFQ pulse, thereby recovering the phase of the clock signal in one bit.
