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…
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…
Single scattering and effective medium description in multilayer cylindrical metamaterials: Application to graphene and metasurface coated cylinders
Charalampos P. Mavidis, Anna C. Tasolamprou, Eleftherios N. Economou +2
Coated and multicoated cylinder systems constitute an appealing metamaterial category, as they allow a very rich and highly tunable response, resulting from the interplay of the ma…
Chirality sensing employing PT-symmetric and other resonant gain-loss optical systems
Ioannis Katsantonis, Sotiris Droulias, Costas M. Soukoulis +3
Molecular chirality detection and enantiomer discrimination are very important issues for many areas of science and technology, prompting intensive investigations via optical metho…
Topological Extraordinary Optical Transmission
K. Baskourelos, O. Tsilipakos, T. Stefański +4
The incumbent technology for bringing light to the nanoscale, the near-field scanning optical microscope, has notoriously small throughput efficiencies - of the order of 10^(-4) -…
Polaritonic cylinders as multifunctional metamaterials: Single scattering and effective medium description
Charalampos P. Mavidis, Anna C. Tasolamprou, Eleftherios N. Economou +2
Polaritonic materials, owing to a strong phonon-polariton resonance in the THz and far-infrared parts of the electromagnetic spectrum, offer both high-index dielectric and metallic…
