    • We present the design of a low loss planar phase switch operating at millimetre and submillimetre wavelengths. The system comprises a superconducting nanostrip that switches the RF signal between the two branches of a microstrip phase circuit. The employment of superconducting components reduces conduction losses to a negligible level. The required cooling below the transition temperature does not add extra effort since all high performance detectors employ superconducting circuits, and are in fact cooled well below the transition temperature of the phase circuit material. The proposed fully planar design allows the switch to be easily integrated into the detector circuit and eventually the realisation of a fully planar receiver. This avoids the use of bulky, expensive and lossy waveguide components and allows the fabrication of reliable and cheaply mass producible polarimeters that are now routinely used in large format CMB arrays.

  • Superconducting subterahertz fast nanoswitch
  • 2007
  • In: JETP Letters. - : Pleiades Publishing Ltd. - 1090-6487 .- 0021-3640. ; 86:4, s. 275-277
  • Journal article (peer-reviewed)abstract
    • A superconducting thin-film nanoswitch for the subterahertz frequency range has been proposed, developed, fabricated, and tested. The switch makes it possible to modulate the microwave signal or switch it between two branches of a circuit with low losses and high speed. The switch can be naturally integrated with superconducting high-sensitive detectors. Its application makes it possible to avoid the use of massive slow mechanical modulators and to improve the measurement accuracy in decisive astrophysical experiments such as the investigation of the anisotropy of the cosmic microwave background.
