Terahertz Volume Plasmon‐Polariton Modulation in All‐Dielectric Hyperbolic Metamaterials

Year: 2026

Type: article

Abstract: The development of plasmonics and related applications in the terahertz range faces limitations due to the intrinsic high electron density of the standard metals. All‐dielectric systems are profitable alternatives, which allows for customized modulation of the optical response upon doping. Here, plasmon‐based hyperbolic metamaterials are realized stacking doped III‐V semiconductors that have been shown to be optically active in the terahertz spectral region. By using a multi‐physics multi‐scale theoretical approach, the role of doping and geometrical characteristics (e.g., thickness, composition, grating) in the modulation of high‐ k plasmon‐polariton modes across the metamaterial is unraveled.
