| 英文摘要 | We have successfully demonstrated a low-noise 0.78-0.95-THz waveguide mixer based on Nb/AlO(x)/Nb superconductor-insulator-superconductor (SIS) junctions integrated with an NbTiN/SiO(2)/Al superconducting inverted microstrip. The mixer employs a twin-junction tuning circuit and an impedance transformer which are designed to achieve both low noise and wideband operation. Corrected for optical input losses in front of the mixer, the double-sideband (DSB) noise temperature is below 120 K (< 3 hf/k(B)) around the local oscillator (LO) frequency of 0.88 THz and at an operating temperature of 2 K. The results represent state-of-the-art performance for mixers in the terahertz frequency range. (C) 2009 The Japan Society of Applied Physics DOI: 10.1143/APEX.2.102201 |
