Mapping Phonon Polaritons with Visible Light
Kiernan E. Arledge, Chase T. Ellis, Nazli Rasouli Sarabi +7
Phonon polaritons (PhPs) are hybrid photon-phonon waves which enable strong light-matter interactions and subdiffractional confinement, potentially empowering applications in sensi…
Giant magneto-optical Kerr enhancement from films on SiC due to the optical properties of the substrate
A. Mukherjee, C. T. Ellis, M. M. Arik +13
We report a giant enhancement of the mid-infrared (MIR) magneto-optical complex Kerr angle (polarization change of reflected light) in a variety of materials grown on SiC. In epita…
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…
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…
Ultra-low-loss Polaritons in Isotopically Pure Materials: A New Approach
Alexander J. Giles, Siyuan Dai, Igor Vurgaftman +12
Conventional optical components are limited to size-scales much larger than the wavelength of light, as changes in the amplitude, phase and polarization of the electromagnetic fiel…
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…
