DOI: 10.1021/acsphotonics.7b00118
Abstract: Mid-infrared nanophotonics can be realized using subdiffractional light localization and field enhancement with surface phonon polaritons in polar dielectric materials. We experimentally demonstrate second-harmonic generation due to the optical field enhancement from critically coupled surface… read more here.

Abstract: Surface phonon polaritons (SPhPs) are attractive alternatives to infrared plasmonics for subdiffractional confinement of infrared light. Localized SPhP resonances in semiconductor nanoresonators are narrow, but that linewidth and the limited extent of the Reststrahlen band… read more here.

DOI: 10.7567/apex.11.082001
Abstract: A strong mode coupling between the guided mode resonance (GMR) and surface phonon polaritons (SPhPs) is numerically demonstrated. The photonic?phononic mode coupling can be mediated by a homogeneous spacer which works as a Fabry?P?rot (FP)… read more here.
