“…On-chip filter bank spectrometers using superconducting resonators as narrow band-separation filters have been theoretically studied [1][2][3] as one of the promising technologies for enabling multi-object broadband spectrometers on next-generation millimeter/submillimeter wave telescopes 4 for astronomy. The advantage of an integrated filter bank spectrometer, such as the proposed instrument DESHIMA (Delft-SRON High z Mapper) 1,2 , over conventional optical spectrometers 5 is the combination of; 1) photon-noise limited point-source sensitivity, ultimately equal to a grating spectrometer, 2) compact size of each filter, which is of the order of the wavelength on chip and independent of frequency resolution, and 3) flexibility for increasing the sampling in either frequency space, or in real space, by arranging multiple filter bank units on a focal plane.…”

We experimentally demonstrate the principle of an on-chip submillimeter wave filter bank spectrometer, using superconducting microresonators as narrow band-separation filters. The filters are made of NbTiN/SiN x /NbTiN microstrip line resonators, which have a resonance frequency in the range of 614-685 GHz-two orders of magnitude higher in frequency than what is currently studied for use in circuit quantum electrodynamics and photodetectors. The frequency resolution of the filters decreases from 350 to 140 with increasing frequency, most likely limited by dissipation of the resonators.

“…The novelty of SuperSpec, and of the conceptually similar DESHIMA, 12,13 is in the adaptation to thin-film lithography. At (sub)millimeter wavelengths, transmission lines are implemented either as microstrips or as coplanar waveguides (CPW).…”

SuperSpec is a pathfinder for future lithographic spectrometer cameras, which promise to energize extra-galactic astrophysics at (sub)millimeter wavelengths: delivering 200-500 km s −1 spectral velocity resolution over an octave bandwidth for every pixel in a telescope's field of view. We present circuit simulations that prove the concept, which enables complete millimeter-band spectrometer devices in just a few square-millimeter footprint. We evaluate both single-stage and two-stage channelizing filter designs, which separate channels into an array of broad-band detectors, such as bolometers or kinetic inductance detector (KID) devices. We discuss to what degree losses (by radiation or by absorption in the dielectric) and fabrication tolerances affect the resolution or performance of such devices, and what steps we can take to mitigate the degradation. Such design studies help us formulate critical requirements on the materials and fabrication process, and help understand what practical limits currently exist to the capabilities these devices can deliver today or over the next few years.

We present a new satellite-based instrument concept that will enable global measurements of atmospheric temperature and humidity profiles with unprecedented resolution and accuracy, compared to currently planned missions. It will also provide global measurements of essential climate variables related to ice clouds that will better constrain global climate models. The instrument is enabled by the use of superconducting detectors coupled to superconducting filterbank spectrometers, operating between 50GHz and 850 GHz. We present the science drivers, the current instrument concept and status, and predicted performance.
