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 …

The ideal material for nanophotonic applications will have a large refractive index at optical
frequencies, respond to both the electric and magnetic fields of light, support large optical …

Transition metal dichalcogenides (TMDs) attract significant attention due to their remarkable
optical and excitonic properties. It was understood already in the 1960s and recently …

Anisotropic planar polaritons-hybrid electromagnetic modes mediated by phonons,
plasmons, or excitons-in biaxial two-dimensional (2D) van der Waals crystals have attracted …

In this Perspective, we discuss the physics and potential applications of planar hyperbolic
metasurfaces (MTSs), with emphasis on their in-plane and near-field responses. After …

Ultra-compact, densely integrated optical components manufactured on a CMOS-foundry
platform are highly desirable for optical information processing and electronic-photonic co …

For decades, the surface-plasmon-polariton wave guided by the interface of simple isotropic
materials dominated the scene. However, in recent times research on electromagnetic …

The transfer-matrix method (TMM) in electromagnetics and optics is a powerful and
convenient mathematical formalism for determining the planewave reflection and …

Optical metasurfaces have recently emerged as the game changer in light manipulation and
opened up new perspectives in many subfields of optics and photonics. Recent …

Moiré superlattices—twisted van der Waals (vdW) structures with small angles—are
attracting increasing attention in condensed matter physics, due to important phenomena …
