Active Tuning of Surface Phonon Polariton Resonances via Carrier Photoinjection
Adam D. Dunkelberger, Chase T. Ellis, Daniel C. Ratchford +10
Surface-phonon polaritons (SPhPs) are attractive alternatives to far-infrared plasmonics for sub-diffractional confinement of light. Localized SPhP resonances in semiconductor nano…

Imaging of anomalous internal reflections of hyperbolic phonon-polaritons in hexagonal boron nitride
Alexander J Giles, Siyuan Dai, Orest J Glembocki +10
We use scanning near-field optical microscopy to study the response of hexagonal boron nitride nanocones at infrared frequencies, where this material behaves as a hyperbolic medium…
