Paper Abstract

We consider mid-infrared (5 - 25 μm), optically cooled detectors based on a microcantilever sensor of the radiation pressure. The significant enhancement of sensitivity is due the combination of low effective temperature (10 K), non-absorption detection and a high quality optical microcavity. Spectrometry applications are analyzed. It is shown that an optically cooled radiation pressure sensor potentially has an order of magnitude better sensitivity than the best conventional uncooled detectors.
