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…
Extremely High Q-factor metamaterials due to Anapole Excitation
Alexey A. Basharin, Vitaly Chuguevsky, Nikita Volsky +2
We demonstrate that ideal anapole metamaterials have infinite Q-factor. We have designed and fabricated a metamaterial consisting of planar metamolecules which exhibit anapole beha…
Dielectric Metamaterials with Toroidal Dipolar Response
Alexey A. Basharin, Maria Kafesaki, Eleftherios N. Economou +4
Toroidal multipoles are the terms missing in the standard multipole expansion; they are usually overlooked due to their relatively weak coupling to the electromagnetic fields. Here…
