Bloch oscillations in arrays of helical waveguides
WeiFeng Zhang, Xiao Zhang, Yaroslav V. Kartashov +2
We study optical Bloch oscillations in the one- and two-dimensional arrays of helical waveguides with transverse refractive index gradient. Longitudinal rotation of waveguides may…
Lieb polariton topological insulators
Chunyan Li, Fangwei Ye, Xianfeng Chen +4
We predict that the interplay between the spin-orbit coupling, stemming from the TE-TM energy splitting, and the Zeeman effect in semiconductor microcavities supporting exci- ton-p…
Quantum mechanical analysis of nonlinear optical response of interacting graphene nanoflakes
Hanying Deng, David Zs. Manrique, Xianfeng Chen +2
We propose a distant-neighbor quantum-mechanical (DNQM) approach to study the linear and nonlinear optical properties of graphene nanoflakes (GNFs). In contrast to the widely used…
Surface modes in plasmonic Bragg fibers with negative average permittivity
Hanying Deng, YiHang Chen, Nicolae C. Panoiu +2
We investigate surface modes in plasmonic Bragg fibers composed of nanostructured coaxial cylindrical metal-dielectric multilayers. We demonstrate that the existence of surface mod…
