Abstract
A broadband photon detector device that operates using a superconducting material is biased at the temperature where the material changes from a superconducting to a non-superconducting state. Photons that strike the material cause a temperature change and a measurable increase in resistivity of the material. Measuring the increase in resistivity allows the detection of the incident photons. This detector is very sensitive because superconducting leads are connected at one end to the superconducting material and at another end to a sensor that measures the changing resistivity, thereby limiting thermal conduction. Thermal conduction is further prevented in another embodiment in which a sensor is electrically and thermally isolated from the superconducting material. This sensor detects the change in resistivity of the superconducting material through detecting a change in an eddy current established in the superconducting material.
