Graphene is an ideal material for hot-electron bolometers due to its low heat capacity and weak electron-phonon coupling. Nanostructuring graphene with quantum-dot constrictions yields detectors of electromagnetic radiation with extraordinarily high

NbN-based detectors can detect light from the granular regime (single or few photons) up to weak continuous photon fluxes at wavelengths ranging from visible light up to mid-IR. The article reports our recent results on a novel linear detector, the w

Twin-slot antennas and coplanar waveguides are a popular choice for coupling signals to state-of-the-art mixers and detectors at terahertz frequencies. Although these sensors show promising performance in terms of noise temperature, they usually also
