Ultraconfined THz Phonon Polaritons in Hafnium Dichalcogenides
R. A. Kowalski, N. S. Mueller, G. Álvarez-Pérez +18
The confinement of electromagnetic radiation to subwavelength scales relies on strong light-matter interactions. In the infrared (IR) and terahertz (THz) spectral ranges, phonon po…
Surface Phonon Polariton Ellipsometry
Giulia Carini, Richarda Niemann, Niclas Sven Mueller +2
Surface phonon polaritons (SPhPs) have become a key ingredient for infrared nanophotonics, owing to their long lifetimes and the large number of polar dielectric crystals supportin…
Spectroscopic and Interferometric Sum-Frequency Imaging of Strongly Coupled Phonon Polaritons in SiC Metasurfaces
Richarda Niemann, Niclas S. Mueller, Sören Wasserroth +4
Phonon polaritons enable waveguiding and localization of infrared light with extreme confinement and low losses. The spatial propagation and spectral resonances of such polaritons…
