Kinetic inductance detectors (KIDs) have come into prominence in the field of far-infrared, sub-millimetre and millimetre-wave astronomy by virtue of their high sensitivity and the ease of fabrication and electronic readout of large format arrays. Beyond astronomy, there are a range of disciplines that can benefit from these advances, including biomedical sensing, process control in manufacturing,...
We report the measured performance characteristics of a broadband (0.2 – 10 THz) bolometer instrument based on thin film superconducting technology. The technology is designed for operation both in liquid helium cryostats but also in an electrical cooling platform. We report a number of significant advantages that accrue to superconducting technology compared to semiconductor devices. Single pixel...
KIDCAM is demonstration of a deployable cryogen-free passive THz imaging technology. A linear focal plane array of Lumped Element Kinetic Inductance Detectors (LEKIDs) is cooled to sub-K temperatures without the consumption of liquid cryogens. The instrument offers extremely high detection sensitivity with video frame rate capability and high spatial resolution to suit many imaging applications. The...
In this paper, we present a hot-electron bolometric detector, which uses the nonlinearities of the heated two-dimensional electron gas medium in AlGaAs/GaAs at room temperature. The cooling process of the electrons is through the phonon-scattering mechanism. The response was measured at the 0.1-0.2 THz frequency range. The response was estimated, showing possible application of these detectors in...
Kinetic inductance detectors (KIDs) provide a promising solution to the problem of producing large format arrays of ultra sensitive detectors for astronomy. Traditionally KIDs have been constructed from superconducting quarter-wavelength or half-wavelength resonator elements capacitively coupled to a co-planar feed line. Photons are detected by measuring the change in quasi-particle density caused...
