Abstract

Continuous wave terahertz spectroscopy based on photomixing offers the attractive feature of detecting both amplitude and phase of the terahertz radiation. Experimentally, it is challenging to achieve sufficient accuracy at a high data acquisition rate. We use two fiber stretchers as fast phase modulators in a symmetric setup. Compared to a mechanical delay stage, the fiber stretchers are rather fast (1kHz), which enables us to record a spectrum up to 1.8 THz with a step size of 1 GHz in only 10 min. We achieve a stability of the optical path difference of around 10 μm and use low-doped Si as an example to demonstrate the performance of our spectrometer.

  15. The opening angle was measured using the knife-edge method; i.e., a metallic edge was translated through the THz beam perpendicular to the propagation direction. The total power behind the edge was focused onto the detector by using two lenses, and a Gaussian beam profile was assumed for the data analysis.
