Development of Superconducting On-chip Fourier Transform Spectrometers
Abstract
Superconducting On-chip Fourier Transform Spectrometers (SOFTS) are broadband, compact and electronic interferometers. Being extremely compact, SOFTS can fit into standard antenna coupled detector architectures. SOFTS will enable kilo-pixel spectro-imaging focal planes enhancing sub-millimeter science; particularly cluster astrophysics / cosmology, CMB-science and line intensity mapping. This proceeding details the development, design and bench-marking of RF on-chip architecture of SOFTS for Ka and W bands.
Additional Information
We demonstrated spectral recovery without noise. Robust recovery with noise is also possible in this framework; we thank Robert Webber (Caltech) for pointing this out. We thank Rick LeDuc at JPL-MDL for device fabrication support. The W-band housing is being made using micro-mill machining by Matt Underhill at ASU. This research is supported by NASA award NNH18ZDA001N-APRA, and by the University of Chicago College Summer Research Scholarship.Attached Files
