Quantitative phase contrast imaging of THz electric fields in a dielectric waveguide.
We apply phase contrast imaging to enable, sharply focused visualization of terahertz waves in electro-optic media. The approach allows quantitative characterization of THz waves in the 60 GHz - 4.5 THz frequency range in a thin dielectric slab and in-focus observation of THz waves in polaritonic structures.
