Maximum non reciprocity in metasurfaces of gyrotropic rods
Ioannis Katsantonis, Constantinos Valagiannopoulos, Anna C. Tasolamprou
Efficiently breaking time-reversal symmetry at the subwavelength scale remains a cornerstone challenge for advanced electromagnetic wave manipulation. This work presents a rigorous…
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…
Minireview on Disordered Optical Metasurfaces
P. Lalanne, A. Dmitriev, C. Rockstuhl +2
The use of coherent wave phenomena to enhance device performance is a cornerstone of modern optics. In juxtaposition to (locally) periodic metasurfaces, their disordered counterpar…
Transparent Multispectral Photonic Electrode for All-Weather Stable and Efficient Perovskite Solar Cells
George Perrakis, Anna C. Tasolamprou, George Kakavelakis +5
Perovskite solar cells (PSCs) are the most promising technology for advancing current photovoltaic performance. However, the main challenge for their practical deployment and comme…
Strong and Broadband Pure Optical Activity in 3D Printed THz Chiral Metamaterials
Ioannis Katsantonis, Maria Manousidaki, Anastasios D. Koulouklidis +9
Optical activity (polarization rotation of light) is one of the most desired features of chiral media, as it is important for many polarization related applications. However, in th…
