Paper Abstract

We observe critical coupling to surface phonon-polaritons in silicon carbide by attenuated total reflection of mid-infrared radiation. Reflectance measurements demonstrate critical coupling by a double-scan of wavelength and incidence angle. Critical coupling occurs when prism coupling loss is equal to losses in silicon carbide and the substrate, resulting in maximal electric field enhancement.
