CCAT: Silicon-Platelet Feedhorns for Submillimeter Wavelengths

May 4, 2026

Author(s)

Jason Austermann, James Beall, Johannes Hubmayr, Matthew Koc, Joel Ullom, Jeffrey Van Lanen, Michael Vissers, Jordan Wheeler

Silicon-platelet feedhorn arrays are an established technology at millimeter wavelengths that, for some applications, can provide significant advantages over traditional direct-machined metal feedhorns. The Prime-Cam focal planes operating in the 350 GHz (

Development of Silicon Micromachined Waveguide Filter-Banks for On-Chip Spectrometers

January 12, 2026

Author(s)

Matthew Koc, Jason Austermann, James Beall, Johannes Hubmayr, Michael Vissers, Jordan Wheeler

Development of high-speed, spatial-mapping spectrometers in the millimeter and far-infrared frequencies would enable entirely new research avenues in astronomy and cosmology. An "on-chip" spectrometer is one such technology that could enable Line Intensity
