Two-dimensional (2D) materials are able to strongly confine light hybridized with collective excitations of atoms, enabling electric-field enhancements and novel spectroscopic applications. Recently, freestanding monolayers of perovskite oxides have been synthesized, which possess highly infrared-active phonon modes and a complex interplay of competing interactions. Here, we show that this new class of 2D materials exhibits highly confined phonon polaritons by evaluating central figures of…

Phonon Polaritons in Monolayers of Hexagonal Boron Nitride.
TLDR
This is the first observation of surface phonon polaritons in single atomic layers and bilayers of hexagonal boron nitride (hBN), and the polariton dispersion and their wavelength-thickness scaling law are altered compared to those of hBN bulk counterparts.
Ab initio calculation of phonon polaritons in silicon carbide and boron nitride.
The ability to use photonic quasiparticles to control electromagnetic energy far below the diffraction limit is a defining paradigm in nanophotonics. An important recent development in this field is
Direct observation of highly confined phonon polaritons in suspended monolayer hexagonal boron nitride
TLDR
Monochromatic electron energy-loss spectroscopy enables the observation of highly confined and ultraslow hyperbolic phonon polaritons in suspended monolayer hexagonal boron nitride, expanding the potential of van der Waals materials for nanophotonic applications.
Tunable Phonon Polaritons in Atomically Thin van der Waals Crystals of Boron Nitride
TLDR
The measured dispersion of polaritonic waves was shown to be governed by the crystal thickness according to a scaling law that persists down to a few atomic layers, likely to hold true in other polar van der Waals crystals and may lead to new functionalities.
Polaritons in van der Waals materials
TLDR
This work discusses polaritons in van der Waals (vdW) materials: layered systems in which individual atomic planes are bonded by weak vdW attraction, thus enabling unparalleled control of polaritonic response at the level of single atomic planes.
Making two-photon processes dominate one-photon processes using mid-IR phonon polaritons
TLDR
This work shows that nanoscale-confined phonon polaritons in polar dielectric materials can be used to develop a bright and efficient spontaneous emitter of photon pairs in the mid-IR/terahertz frequency ranges, and shows that such two-photon emission processes can occur on nanosecond time scales.
Highly confined low-loss plasmons in graphene-boron nitride heterostructures.
TLDR
This Article exploits near-field microscopy to image propagating plasmons in high-quality graphene encapsulated between two films of hexagonal boron nitride (h-BN), and finds unprecedentedly low plasmon damping combined with strong field confinement and confirms the high uniformity of this plAsmonic medium.
Phonon Polaritonics in Two-Dimensional Materials.
TLDR
A first-principles expression for the conductivity of a polar monolayer specified by the wave-vector-dependent LO and TO phonon dispersions is derived, and it is revealed that the phonon polariton of 2D is simply the LO phonon of the 2D system.
Sub-diffractional volume-confined polaritons in the natural hyperbolic material hexagonal boron nitride.
TLDR
Three-dimensionally confined 'hyperbolic polaritons' in boron nitride nanocones that support four series (up to the seventh order) modes in two spectral bands are reported on.
Breakdown of Optical Phonons' Splitting in Two-Dimensional Materials.
TLDR
Analysis of the long-wavelength dispersion of longitudinal and transverse optical phonon modes in polar two-dimensional materials, multilayers, and their heterostructures shows that at variance with the three-dimensional case these modes are degenerate at the zone center but the macroscopic electric field associated with the longitudinal-optical modes gives rise to a finite slope at the zones center in their corresponding phonon dispersions.
