Spin-Orbit Interaction of Light Enabled by Negative Coupling in High Quality Factor Optical Metasurfaces
Wenlong Gao, Basudeb Sain, Thomas Zentgraf
We study the negative couplings amid local resonances of photonic metasurfaces. In our analysis, we discover pseudo-spin-orbit coupled bulk modes leading to lines of circularly pol…
Efficient frequency conversion with geometric phase control in optical metasurfaces
Bernhard Reineke Matsudo, Basudeb Sain, Luca Carletti +5
Metasurfaces have appeared as a versatile platform for miniaturized functional nonlinear optics due to their design freedom in tailoring wavefronts. The key factor that limits its…
Nonlinear imaging of nanoscale topological corner states
Sergey S. Kruk, Wenlong Gao, Duk-Yong Choi +3
Topological states of light represent counterintuitive optical modes localized at boundaries of finite-size optical structures that originate from the properties of the bulk. Being…
Extremely broadband topological surface states in a photonic topological metamaterials
Minkyung Kim, Dasol Lee, Wenlong Gao +4
Metamaterials, artificially engineered materials consisting of subwavelength unit cell, have shown potentials in light manipulation with their extraordinary optical properties. Esp…
Observation of photonic Fermi arcs in topological metamaterials
Biao Yang, Qinghua Guo, Ben Tremain +8
The discovery of topological phases introduces new perspectives and platforms for various interesting physics originally investigated in quantum context and then, on an equal footi…
Three dimensional photonic Dirac points in metamaterials
Qinghua Guo, Biao Yang, Lingbo Xia +5
Topological semimetals, representing a new topological phase that lacks a full bandgap in bulk states and exhibiting nontrivial topological orders, recently have been extended to p…
