Control of Group Velocity Based on Nonlinear Kerr Effect in a Plasmonic Superlattice
We propose a plasmonic superlattice with nonlinear Kerr medium in defect layer to realize slow light effect and demonstrate the group velocity control at telecom waveband (1550 nm) by peak intensityExpand

Polarization conversion based on an all-dielectric metasurface for optical fiber applications
Polarization conversion (PC) in optical fiber is a very important operation in practice. To date, however, PC in fiber is usually achieved by coupling an external bulk element, or using theExpand
