Voltage-biased high-T/sub c/ superconducting infrared bolometers with strong electrothermal feedback

Abstract

In the current generation of high-T/sub c/ bolometers the thermal conductance is often chosen for a short time-constant rather than for optimal sensitivity. We describe a novel bolometer bias and readout scheme that promises to relax this constraint. Voltage bias of the superconductor results in strong negative electrothermal feedback that greatly reduces… (More)
