The authors' main claim Here, we demonstrate a system composed of silver nanocubes deposited on a SiC polar dielectric, which experimentally realizes the antisymmetric-image-phonon-polaritons (AIPhPs) mode: a hybridized SPhPs mode that can confine mid-infrared radiation to extremely small mode-volumes, almost a billion times smaller than their free-space volume, with quality-factors an order-of-magnitude greater than those of surface-plasmons or graphene-plasmons, surpassing values of 180.

Original abstract

Surface-polaritons play a pivotal role in strong light-matter interactions at the nanoscale due to their ability to confine light to deep subwavelength dimensions. A promising class of materials exhibiting such polaritonic response are polar dielectrics, which support surface phonon polaritons (SPhPs). While SPhPs offer significantly lower losses compared to other polaritons, their potential has been underutilized due to limited ability to reach large continent factors. Here, we demonstrate a system composed of silver nanocubes deposited on a SiC polar dielectric, which experimentally realizes the antisymmetric-image-phonon-polaritons (AIPhPs) mode: a hybridized SPhPs mode that can confine mid-infrared radiation to extremely small mode-volumes, almost a billion times smaller than their free-space volume, with quality-factors an order-of-magnitude greater than those of surface-plasmons or graphene-plasmons, surpassing values of 180.
