Phase Modulation Extension
Phase modulation for TeraScan or TeraBeam
cw terahertz spectroscopy based on photomixing offers the attractive feature of detecting both amplitude and phase of the terahertz wave. Determining the phase requires a modulation of the optical path length, or the terahertz frequency. The Phase Modulation Package offers a particularly fast and accurate technique to scan the terahertz phase, by using a symmetric setup with two fiber stretchers wound around piezo actuators. Users can thus retrieve full information on phase and amplitude of the terahertz wave - with single-Megahertz resolution!
