High-efficiency nonlocal reflection-type vortex beam generation based on bound states in the continuum

Momentum-space polarization vortices centered at symmetry-protected bound states in the continuum of a periodic structure, e.g. photonic crystal slab, provide a novel nonlocal approach to generate vortex beams. This approach enjoys a great convenience of no precise alignment requirements, although t...
