Negative reflection of polaritons at the nanoscale in a low-loss natural medium
Gonzalo Alvarez-Perez, Jiahua Duan, Javier Taboada-Gutierrez +10
Negative reflection occurs when light is reflected towards the same side of the normal to the boundary from which it is incident. This exotic optical phenomenon, which provides a n…
Enhanced Light-Matter Interaction in B-10 Monoisotopic Boron Nitride Infrared Nanoresonators
M. Autore, I. Dolado, P. Li +10
Phonon-polaritons, mixed excitations of light coupled to lattice vibrations (phonons), are emerging as a powerful platform for nanophotonic applications. This is because of their a…
Unraveling Ultrafast Photoionization in Hexagonal Boron Nitride
Lianjie Xue, Song Liu, Yang Hang +17
The non-linear response of dielectrics to intense, ultrashort electric fields has been a sustained topic of interest for decades with one of its most important applications being f…
Real-space observation of vibrational strong coupling between propagating phonon polaritons and organic molecules
Andrei Bylinkin, Martin Schnell, Marta Autore +10
Phonon polaritons (PPs) in van der Waals (vdW) materials can strongly enhance light-matter interactions at mid-infrared frequencies, owing to their extreme infrared field confineme…
Guided Mid-IR and Near-IR Light within a Hybrid Hyperbolic-Material/Silicon Waveguide Heterostructure
Mingze He, Sami I. Halimi, Thomas G. Folland +6
Silicon waveguides have enabled large-scale manipulation and processing of near-infrared optical signals on chip. Yet, expanding the bandwidth of guided waves to other frequencies…
Collective near-field coupling in infrared-phononic metasurfaces for nano-light canalization
Peining Li, Guangwei Hu, Irene Dolado +10
Polaritons, coupled excitations of photons and dipolar matter excitations, can propagate along anisotropic metasurfaces with either hyperbolic or elliptical dispersion. At the tran…
Image polaritons in boron nitride for extreme polariton confinement with low losses
In-Ho Lee, Mingze He, Xi Zhang +8
Polaritons in two-dimensional materials provide extreme light confinement that is difficult to achieve with metal plasmonics. However, such tight confinement inevitably increases o…
Refractive Index-Based Control of Hyperbolic Phonon-Polariton Propagation
Alireza Fali, Samuel T. White, Thomas G. Folland +7
Hyperbolic phonon polaritons (HPhPs) are generated when infrared photons couple to polar optic phonons in anisotropic media, confining long-wavelength light to nanoscale volumes. H…
Infrared hyperbolic metasurface based on nanostructured van der Waals materials
Peining Li, Irene Dolado, Francisco Javier Alfaro-Mozaz +7
Metasurfaces with strongly anisotropic optical properties can support deep subwavelength-scale confined electromagnetic waves (polaritons) that promise opportunities for controllin…
Probing hyperbolic polaritons using infrared attenuated total reflectance micro-spectroscopy
Thomas G. Folland, Tobias W. W. Maß, Joseph R. Matson +7
Hyperbolic polariton modes are highly appealing for a broad range of applications in nanophotonics, including surfaced enhanced sensing, sub-diffractional imaging and reconfigurabl…
Reconfigurable Mid-Infrared Hyperbolic Metasurfaces using Phase-Change Materials
Thomas G. Folland, Alireza Fali, Samuel T. White +7
Metasurfaces offer the potential to control light propagation at the nanoscale for applications in both free-space and surface-confined geometries. Existing metasurfaces frequently…
