Ultra-sensitive heterodyne detection at room temperature in the atmospheric windows

Ultra-sensitive heterodyne detection at room temperature in the atmospheric windows

We report room temperature heterodyne detection of a quantum cascade laser beaten with a local oscillator on a unipolar quantum photodetector in two different atmospheric windows, at 4.8 µm and 9 µm. A noise equivalent power of few pW is measured by employing an active stabilization technique in whi...
