Maximum non reciprocity in metasurfaces of gyrotropic rods
Ioannis Katsantonis, Constantinos Valagiannopoulos, Anna C. Tasolamprou
The paper develops an analytical model to quantify and maximize nonreciprocal scattering from magnetically biased gyrotropic rods, and uses the results to design metasurfaces that…
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…
Ultracompact, dynamically controllable circularly polarized laser enabled by chiral metasurfaces
Ioannis Katsantonis, Anna Tasolamprou, Eleftherios Economou +2
We demonstrate a simple, low-cost and ultracompact chiral resonant metasurface design, which, by strong local coupling to a quantum gain medium (quantum emitters), allows to implem…
