ABSTRACT:
A broadband photon detector device which operates using a superconducting material is biased at the temperature where the material changes from a superconducting to a non-superconducting state. Photons which strike said material cause a temperature rise and a measurable increase in resistivity of the material. Measuring the increase in resistivity allows the detection of the incident photons.
