Lossless propagation of gain-compensated graphene plasmons
Andrianos Sygrimis, Giorgos P. Tsironis
Graphene supports surface plasmon polaritons with extreme field confinement and electrical tunability, but these waves are typically short-lived due to ohmic loss in the sheet. We…
Graphene and active metamaterials: theoretical methods and physical properties
Marios Mattheakis, Giorgos P. Tsironis, Efthimios Kaxiras
The interaction of light with matter has triggered the interest of scientists for long time. The area of plasmonics emerges in this context through the interaction of light with va…
Resonant Combinatorial Frequency Generation Induced by a PT-symmetric Periodic Layered Stack
Oksana V. Shramkova, Giorgos P. Tsironis
The nonlinear interaction of waves in PT-symmetric periodic stacks with an embedded nonlinear anisotropic dielectric layer illuminated by plane waves of two tones is examined. The…
Small-world networks of optical fiber lattices
F. Perakis, M. Mattheakis, G. P. Tsironis
We use a simple dynamical model and explore coherent dynamics of wavepackets in complex networks of optical fibers. We start from a symmetric lattice and through the application of…
