Abstract: To increase efficiency of optical control of phase shifting elements, arrangements comprising optical lenses are presented. The optical lenses may be arranged in reflective arrays so as to focus light from a light source on a phase shifting element, which may be placed in a feed point of an antenna, such as for example a lithographic antenna. In some embodiments, thus both optical controlling radiation and radio frequency, RF, power are concentrated in substantially the same place.

Abstract: A superconducting thermal detector (bolometer) of THz (sub-millimeter) wave radiation based on sensing the change in the amplitude or phase of a resonator circuit, consisting of a capacitor (Csh) and a superconducting temperature dependent inductor (2) where the said inductor is thermally isolated from the heat bath (chip substrate (3)) by micro-suspensions (11). The bolometer design includes a thin film inductor located on the membrane, a single or/and multi-layered thin film capacitor, and a thin film absorber of incoming radiation. The bolometer design can also include a lithographic antenna with antenna termination and/or a back reflector beneath the membrane for optimal wavelength detection by the resonance circuit. The superconducting thermal detector (bolometer) and arrays of these detectors operate in a temperature range from 1 Kelvin to 10 Kelvin.
