Aims. Future astrophysics and cosmic microwave background space missions operating in the far-infrared to millimetre part of the spectrum will require very large arrays of ultra-sensitive detectors in combination with high multiplexing factors and efficient lownoise and low-power readout systems. We have developed a demonstrator system suitable for such applications. Methods. The system combine...
Abstract Superconducting nanowire single photon detectors (SNSPDs) are typically used as single-mode-fiber-coupled single-pixel detectors, but large area increasingly critical for applications ranging from microscopy to free-space quantum communications. However, the long meander-line length of such large-area SNSPDs results in a proportionately kinetic inductance that affects waveform generate...
The complex conductivity of a superconducting thin film is related to the quasiparticle density, which depends on physical temperature and can also be modified by external pair breaking with photons phonons. This relationship forms underlying operating principle Kinetic Inductance Detectors (KIDs), where detection threshold governed energy gap. We investigate electromagnetic properties thin-fil...
We have developed a passive 350 GHz (850 μm) video-camera to demonstrate lumped element kinetic inductance detectors (LEKIDs)--designed originally for far-infrared astronomy--as an option for general purpose terrestrial terahertz imaging applications. The camera currently operates at a quasi-video frame rate of 2 Hz with a noise equivalent temperature difference per frame of ∼0.1 K, which is cl...
In this paper, we present modeling and characterization of CNT-based TSVs to be used in high-frequency RF applications. We have developed an integrated model of CNT-based TSVs by incorporating the quantum confinement effects of CNTs with the kinetic inductance phenomenon at high frequencies. Substrate parasitics have been appropriately modeled as a monolithic microwave capacitor with the resona...
We propose an on-chip spectrometer camera for sub-millimeter astronomy. The camera will be installed to the focal plane of a telescope and be operated at 0.1 K. The camera is composed of three kinds superconducting circuits, such as wideband antennas, band pass filters (BPFs), and Microwave Kinetic Inductance Detectors (MKID) [1]. All components are fabricated on the same chip by the standard p...
