Superconducting Coplanar Waveguide Filters for Submillimeter Wave On-Chip Filterbank Spectrometers
We show the first experimental results which prove that superconducting NbTiN coplanar-waveguide resonators can achieve a loaded Q factor in excess of 800 in the 350 GHz band. These resonators can be used as narrow band pass filters for on-chip filter bank spectrometers for astronomy. Moreover, the low-loss coplanar waveguide technology provides an interesting alternative to microstrip lines fo...
متن کاملSuperconducting On-Chip Spectrometery for Millimeter-submillimeter Wave Astronomy
Since the birth of astrophysics, astronomers have been using free-space optics to analyze light falling on Earth. In the future however, thanks to the advances in photonics and nanoscience/nanotechnology, much of the manipulation of light might be carried out using not optics but confined waveguides, or circuits, on a chip. This new generation of instruments will be not only extremely compact, ...
متن کاملMiniaturization of superconducting coplanar waveguide bandpass filters by cross coupling
For more size reduction of the high temperature superconducting coplanar waveguide (CPW) bandpass filter (BPF), we introduce the design method of the meanderline CPW quarter-wavelength resonator BPF. The exact admittanceand susceptance-inverters are calculated by using the 2.5-dimensional electromagnetic field simulator. The prototype YBCO miniaturized BPF (center frequency =10GHz, n=3, band wi...
متن کاملMiniaturized High-Temperature Superconducting Microstrip and Coplanar Waveguide Filters
Two types of miniaturized high-temperature superconducting filters are described in this paper. The first type is developed by using small-sized microstrip spiral resonators, and the second type by coplanar waveguide quarter-wavelength resonators. The filters have significantly reduced size compared with many previous HTS filters. They are designed by employing an electromagnetic simulator in c...
متن کاملMicromachined Waveguide Components for Submillimeter-wave Applications
The high cost of fabricating waveguide components is one of the primary factors limiting the development of terahertz technology. This paper reviews the development of an inexpensive micromachining technology that is suitable for the frequency range from 500 GHz through 5 THz. Our first effort was a 585 GHz direct detector that allowed us to measure the beam patterns of our new micromachined ho...
