Development of Superconducting On-chip Fourier Transform Spectrometers
Abstract
Superconducting On-chip Fourier Transform Spectrometers (SOFTS) are broadband, ultra-compact and electronic interferometers. SOFTS will enable kilo-pixel spectro-imaging focal planes, enhancing sub-millimeter astrophysics and cosmology. Particular applications include cluster astrophysics, cosmic microwave background (CMB) science, and line intensity mapping. This article details the development, design and bench-marking of radio frequency (RF) on-chip architecture of SOFTS for Ka and W-bands.

Special Issue: Low Temperature Detectors LTD19, Part III We thank Robert Webber (Caltech) for pointing out noise spectral construction is possible with our framework [6]. 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. Undergraduate students C. Bell, E. Linden and E. Rapaport assisted with hardware assembly and participated through JPL/Caltech SURF.
