Low-loss far-infrared surface phonon polaritons in suspended SrTiO3 nanomembranes

Konnor Koons, Hans A. Bechtel, Javier Taboada-Gutiérrez +6

Phonon polaritons (PhPs), excitations arising from the coupling of light with lattice vibrations, enable light confinement and local field enhancement, which is essential for vario…
