Strong Coupling of Epsilon-Near-Zero Phonon Polaritons in Polar Dielectric Heterostructures
Nikolai Christian Passler, Christopher R. Gubbin, Thomas Graeme Folland +7
We report the first observation of epsilon near zero (ENZ) phonon polaritons in an ultrathin AlN film fully hybridized with surface phonon polaritons (SPhP) supported by the adjace…
Second Harmonic Generation from Phononic Epsilon-Near-Zero Berreman Modes in Ultrathin Polar Crystal Films
Nikolai Christian Passler, Ilya Razdolski, D. Scott Katzer +4
Immense optical field enhancement was predicted to occur for the Berreman mode in ultrathin films at frequencies in the vicinity of epsilon near zero (ENZ). Here, we report the fir…
Second harmonic generation from strongly coupled localized and propagating phonon-polariton modes
Ilya Razdolski, Nikolai Christian Passler, Christopher R. Gubbin +8
We experimentally investigate second harmonic generation from strongly coupled localized and propagative phonon polariton modes in arrays of silicon carbide nanopillars. Our result…
Controlling the Infrared Dielectric Function through Atomic-Scale Heterostructures
Daniel C. Ratchford, Christopher J. Winta, Ioannis Chatzakis +20
Surface phonon polaritons (SPhPs) - the surface-bound electromagnetic modes of a polar material resulting from the coupling of light with optic phonons - offer immense technologica…
