The schematic of spherulite prism working as a structured light sorter. The 5CB molecule is optically anisotropic with its refractive index ne along the longer axis and no along the short axis. The spherulite is constructed by these molecules with the longitudinal axis along the azimuthaldirection of the material, exhibiting the cylindrically anisotropy: nA = ne and nR = no, which is mimicking the metamaterials consisted of concentric multi-layered structure. Such a spherulite is cut into a prism and can be used to sort two optical vector vortices with radial and azimuthal polarizations from a circularly polarized beam.
