Sfiligoj, C. Yates, S.J.C. Baselmans, J.J.A. Thoen, D.J. Javadzadeh, S.M.H. Van der Werf, P.P. Baryshev, A.M. Klapwijk, T.M. Faculty Applied Sciences Department QN/Quantum Nanoscience Date 2013-07-15 Abstract 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/SiNx/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.
