Enhanced THz third-harmonic generation in graphene via hot-carriers in a topological cavity
Spyros Doukas, Ioannis Katsantonis, Thomas Koschny +2
Graphene is a promising material for nonlinear THz applications owing to its high third-order susceptibility and tunable optical properties. Its strong nonlinear response, driven b…

Multiple truly topological unidirectional surface magnetoplasmons at terahertz frequencies
Shengquan Fan, Tianjing Guo, Binbin Zhou +7
Unidirectional propagation based on surface magnetoplasmons (SMPs) has recently been realized at the interface of magnetized semiconductors. However, usually SMPs lose their unidir…

Robust multimode interference and conversion in topological unidirectional surface magnetoplasmons
Chao Liu, Ziyang Zhao, Tianjing Guo +6
We have theoretically investigated surface magnetoplasmons (SMPs) in a yttrium-iron-garnet (YIG) sandwiched waveguide. The dispersion demonstated that this waveguide can support to…
