Generation of perfect vortex and vector beams based on Pancharatnam-Berry phase elements
Yachao Liu, Yougang Ke, Junxiao Zhou +4
Perfect vortex beams are the orbital angular momentum (OAM)-carrying beams with fixed annular intensities, which provide a better source of OAM than traditional Laguerre- Gaussian…

Spin photonics and spin-photonic devices with dielectric metasurfaces
Yachao Liu, Shizhen Chen, Yougang Ke +3
Dielectric metasurfaces with spatially varying birefringence and high transmission efficiency can exhibit exceptional abilities for controlling the photonic spin states. We present…

Realization of spin-dependent splitting with arbitrary intensity patterns based on all-dielectric metasurfaces
Yougang Ke, Yachao Liu, Yongli He +3
We report the realization of spin-dependent splitting with arbitrary intensity patterns based on all-dielectric metasurface. Compared to the plasmonic metasurfaces, the all-dielect…
