Generating optical vortex beams by momentum-space polarization vortices centered at bound states in the continuum
Bo Wang, Wenzhe Liu, Maoxiong Zhao +7
An optical vortex (OV) is a beam with spiral wave front and screw phase dislocation. This kind of beams is attracting rising interest in various fields. Here we theoretically propo…

Circularly polarized states spawning from bound states in the continuum
Wenzhe Liu, Bo Wang, Yiwen Zhang +6
Bound states in the continuum in periodic photonic systems like photonic crystal slabs are proved to be accompanied by vortex polarization singularities on the photonic bands in th…
