Continuous Goos-Hänchen Shift of Vortex Beam via Symmetric Metal-Cladding Waveguide
Goos-Hänchen shift provides a way to manipulate the transverse shift of an optical beam with sub-wavelength accuracy. Among various enhancement schemes, millimeter-scale shift at near-infrared range has been realized by a simple symmetrical metal-cladding waveguide structure owing to its unique ultr...
