Ultrabroadband nanocavity of hyperbolic phonon polaritons in 1D-like α-MoO3
Ingrid D. Barcelos, Thalita A. Canassa, Rafael A. Mayer +7
The exploitation of phonon-polaritons in nanostructured materials offers a pathway to manipulate infrared (IR) light for nanophotonic applications. Notably, hyperbolic phonons pola…

Group velocity modulation and wavelength tuning of phonon-polaritons by engineering dielectric-metallic substrates
Flávio H. Feres, Rafael A. Mayer, Ingrid D. Barcelos +2
In analogy to the observed for single plasmon-polaritons, we show that subdiffractional hyperbolic phonon-polariton (HP2) modes confined in hexagonal boron nitride (hBN) nanocrysta…

Observation of plasmon-phonon coupling in natural 2D graphene-talc heterostructures
Ingrid D. Barcelos, Alisson R. Cadore, Ananias B. Alencar +8
Two-dimensional (2D) materials occupy noteworthy place in nanophotonics providing for subwavelength light confinement and optical phenomena dissimilar to those of their bulk counte…
