“…Theory has predicted that the collective dynamics of electrons on both the open-segment and closed Fermi surfaces in Weyl semimetals with broken time reversal symmetry leads to the creation of Fermi arc plasmons with hyperbolic dispersion and chiral nature, that could allow for tight focusing of collimated, nonreciprocal surface plasmon waves with frequency-dependent directionality . Such hyperbolic plasmons have been demonstrated in WTe 2 and ZrSiSe very recently. , Furthermore, Weyl semimetals in the presence of a magnetic field are predicted to support two types of highly confined 3D topological plasmons with anisotropic dispersions, from linear to parabolic or even hyperbolic bands . Hybridizing such materials with suitable metamaterial structures could provide additional degrees of freedom to control and enhance light–matter interaction.…”

“…In addition, topological semimetals are theoretically predicted to support rich electrodynamics resulting in unconventional propagation of light. − This includes tunable response to external perturbations such as heat or magnetic fields, as well as hyperbolic dispersion. For example, Cd 3 As 2 shows thermo-optic shifts larger than conventional III–V semiconductors, while Co 3 Sn 2 S 2 exhibits giant magneto-optical response.…”

In recent years, this approach has been extended to the realm of topological materials, providing a new avenue to access nontrivial features of their electronic band structure. In this review, we survey various topological material classes from a photonics standpoint, including crystal growth and lithographic structuring methods. We discuss how exotic electronic features such as spin-selective Dirac plasmon polaritons in topological insulators or hyperbolic plasmon polaritons in Weyl semimetals may give rise to unconventional magneto-optic, nonlinear, and circular photogalvanic effects in metamaterials across the visible to infrared spectrum. Finally, we dwell on how these effects may be dynamically controlled by applying external perturbations in the form of electric and magnetic fields or ultrafast optical pulses. Through these examples and future perspectives, we argue that topological insulator, semimetal and superconductor metamaterials are unique systems to bridge the missing links between nanophotonic, electronic, and spintronic technologies.

Weyl semimetals are topological materials whose electron quasiparticles obey the Weyl equation. They possess many unusual properties that may lead to new applications. This is a tutorial review of the optical properties and applications of Weyl semimetals. We review the basic concepts and optical responses of Weyl semimetals, and survey their applications in optics and thermal photonics. We hope this pedagogical text will motivate further research on this emerging topic.
