AbstractPhonon polaritons are quasiparticles resulting from the coherent coupling of photons with optical phonons in polar dielectrics1. Owing to their exceptional ability to confine electric fields to deep-subwavelength scales with low loss, they are uniquely poised to enable a suite of applications beyond the reach of conventional photonics, such as subdiffraction imaging2 and near-field energy transfer3,4,5.
