Abstract
Terahertz radiation is becoming increasingly important for a broad range of (potential) applications. However, photonic applications are typically more advanced in other regions of the electromagnetic spectrum than in the terahertz region. During the past years, it has become evident that quantum materials with massless electrons, such as graphene and topological insulators, can play a crucial role in overcoming the challenges associated with terahertz photonic applications. In particular, we have recently used quantum metamaterials, which include a photonic structure to increase light-matter interaction, to demonstrate record-high nonlinear susceptibilities, near-milliwatt generation of third harmonic signal, and THz-induced emission of visible light.
