Abstract: Quantum cascade lasers combine unique features in the framework of THz sources, namely compactness and mW output power. In addition, owing to an intrinsically low phase-noise level, they are suitable for frequency and phase stabilization, which makes them attractive sources for frequency metrology applications, and able to overcome the power limits of current microwave-traceable THz emitters. In this contribution, we address metrological grade THz quantum cascade lasers from their intrinsic spectral feature to the use of optical frequency combs as frequency reference.
Keywords: Terahertz generation, Coherent detection, Frequency metrology.
