Towards Measuring Terahertz Photon Statistics by a Superconducting Bolometer

Sensors, 2021
Statistical distributions of the analog readings of an antenna-coupled THz superconducting bolometer were measured and analyzed under a special type of irradiation by low-energy fluxes of THz photons with Poisson photon statistics and controllable mean ...

Responsivity and Noise Equivalent Power of a Single Cold-Electron Bolometer

Applied Sciences (Switzerland), 2021
We have developed a single-pixel capacitively coupled Cold-Electron Bolometer (CEB) and characterized it in the current-biased regime. The most attractive feature of the CEB is effective electron self-cooling of the absorber, which leads to a lower ...

Uncooled sub-GHz spin bolometer driven by auto-oscillation

Nature Communications, 2021
Goto et al present a bolometer based around the heat generation in magnetic tunnel junctions under auto-oscillation conditions. Unlike superconducting bolometers, the presented device operates at room temperature and sub-GHz frequencies, opening ...
