In this article, novel, phonon-based silicon carbide nanopillar antenna arrays are described. Using fabricated SiC structures, sub-diffractional, localized resonances are observed with exceptionally high quality factors (40-305) and corresponding high modal confinements in the mid-infrared (IR) spectral region. These results exceed the theoretical limit of plasmonic systems and establish a basis for nanophotonics in the mid-IR and beyond, opening the door to a wide range of applications in sensing, lithography, optical circuitry and more.
