DOI: 10.1364/ao.463459

Abstract: Scalar and vector vortex beams are characterized of a helical wavefront but different polarized states, which result in different applications. In this paper, we design and fabricate a plasmonic metasurface based on the geometric phase… read more here.

DOI: 10.1364/oe.485396

Abstract: Based on coherent beam combining, we propose a method for generating the perfect vectorial vortex beams (VVBs) with a specially designed radial phase-locked Gaussian laser array, which is composed of two discrete vortex arrays with… read more here.

DOI: 10.1364/oe.537116

Abstract: With the superpositions of spin and orbital angular momentum, vectorial vortex beams (VVBs) have attracted great attention in recent years. Many approaches have been developed to generate such beams, but high-power output is not supported.… read more here.

DOI: 10.1364/ol.564618

Abstract: Vectorial vortex beams (VVBs) exhibit unique polarization and mode characteristics, positioning them as promising candidates for advanced photonic applications. However, the efficient de-/multiplexing of VVBs, particularly across multiple wavelengths, remains a significant challenge. To address… read more here.
