While these evanescent modes have been thoroughly characterized by near-field mapping or far-field intensity measurements over the last decade, far-field optical experiments also providing phase information are less common. In this paper, we study surface phonon polaritons at the gallium phosphide (GaP)-air interface in the momentum domain using the Otto-type prism coupling geometry.
