Description
A convenient light source together with a suitable detector comprise the basic setup for sensing and imaging applications.
We present a flexible terahertz (THz) frequency comb source operating at room temperature that provides great freedom in the spectral content design. A robust setup merges two mature technologies, namely optical fibre communications and opto-electronic frequency conversion (photomixing). The quality of the generated THz comb is proven by the observation of the pressure-dependent collisional broadening of an ammonia molecular absorption line. Our presented THz source is expected to enhance the sensitivity and accuracy of sensing applications in general.
