Abstract

As applications in fields like security or medicine require sensitive schemes in order to detect IR photons, an interesting strategy consists in converting weak IR signals into the optical domain where detectors with single photon sensitivity are readily available. We introduce here a novel platform for ultra-sensitive conversion and detection of far and mid-infrared signals, inspired by cavity optomechanics. The conversion process, relying on the intrinsic ability of specific molecular vibrations to interact both with optical and IR fields, is optimized through the use of doubly resonant nano-antennas. Our study demonstrates noise levels improving on state of the art for IR detectors operating at room temperature and opens the path to single IR photon detection devices.
