Ultrafast Control of Lifetime in High Q Anisotropic Plasmon Polaritons
Romain Tirole, Giacomo Venturi, Emroz Khan +6
Losses are a major roadblock in the technological implementation of surface plasmons at optical frequencies. The recent emergence of MoOCl2, a correlated van-der-Waals material wit…

Intrinsic plasmon canalization in the biaxial van der Waals crystal MoOCl
Farid Aghashirinov, Andrea Mancini, Lin Nan +4
Anisotropic polaritons in low-symmetry crystals allow for subwavelength confinement and directional routing of light. The most extreme form of such anisotropy arises at the topolog…

Visible-frequency hyperbolic plasmon polaritons in a natural van der Waals crystal
Giacomo Venturi, Andrea Mancini, Nicola Melchioni +2
Controlling light at subwavelength scales is one of the main challenges of nanophotonics. Leveraging hyperbolic polaritons supporting arbitrarily large wavevectors can lead to extr…
