Nanostructured surfaces with designed optical functionalities, such as metasurfaces, allow
efficient harvesting of light at the nanoscale, enhancing light–matter interactions for a wide …

In this brief review, we summarize and elaborate on some of the nomenclature of polaritonic
phenomena and systems as they appear in the literature on quantum materials and …

Infrared spectroscopy provides unique information on the composition and dynamics of
biochemical systems by resolving the characteristic absorption fingerprints of their …

Here, we review the progress and most recent advances in phonon-polaritonics, an
emerging and growing field that has brought about a range of powerful possibilities for mid …

Strong coupling between optical modes can be implemented into nanophotonic design to
modify the energy–momentum dispersion relation. This approach offers potential avenues …

Polaritons in two-dimensional materials provide extreme light confinement that is difficult to
achieve with metal plasmonics. However, such tight confinement inevitably increases optical …

Anisotropy has been a key property employed in the design of optical components for
hundreds of years. However, in recent years there has been growing interest in polaritons …

The recent discovery of in‐plane hyperbolic phonon polaritons in biaxial polar crystal—α‐
MoO3, has aroused a huge research upsurge on anisotropic photonic quasiparticles in van …

Vibrational strong coupling (VSC), the strong coupling between optical resonances and the
dipolar absorption of molecular vibrations at mid‐infrared frequencies, holds the great …

Bound state in the continuum (BIC) in all-dielectric metasurfaces can strongly enhance light-
matter interactions in mid-infrared range, owing to their extreme field confinement with low …
