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…
Multiresonant metasurfaces for arbitrarily-broadband pulse chirping and dispersion compensation
Odysseas Tsilipakos, Thomas Koschny
We show that ultrathin metasurfaces with a specific multiresonant response can enable simultaneously arbitrarily-strong and arbitrarily-broadband dispersion compensation, pulse (de…
The local density of optical states in the 3D band gap of a finite photonic crystal
Charalampos P. Mavidis, Anna C. Tasolamprou, Shakeeb B. Hasan +5
A three-dimensional (3D) photonic band gap crystal is an ideal tool to completely inhibit the local density of optical states (LDOS) at every position in the crystal throughout the…
Wavefront manipulation based of the excitation of bound states in dielectric photonic crystals and bilayer metasurfaces
Anna C. Tasolamprou, Maria Kafesaki, Thomas Koschny +1
We present the study of bound surface modes sustained at the termination of truncated bulk dielectric photonic crystals and isolated metasurfaces of dielectric meta-atoms. We discu…
Metasurfaces with Interleaved Electric and Magnetic Resonances for Broadband Arbitrary Group Delay in Reflection
Odysseas Tsilipakos, Thomas Koschny, Costas M. Soukoulis
Metasurfaces impart phase discontinuities on impinging electromagnetic waves that are typically limited to 0-2. Here, we show that they can break free from this limitation and s…
Nonlinearity in the Dark: Broadband Terahertz Generation with Extremely High Efficiency
Ming Fang, Nian-Hai Shen, Wei E. I. Sha +3
Plasmonic metamaterials and metasurfaces offer new opportunities in developing high performance terahertz emitters and detectors beyond the limitations of conventional nonlinear ma…
