摘要
In recent years,optical skyrmions have garnered increasing attention for their ability to introduce new degrees of freedom in manipulating optical fields.While most research has focused on creating innovative optical topological states such as merons and hopfions,there has been limited exploration into their manipulation,which hinders practical applications in this field.In this study,we utilize a hybrid multi-zone filter to induce a Hall effect-like splitting of optical Stokes skyrmions(HESSs),enabling effective separation and manipulation.By manipulating the horizontal phase gradient parameter,we independently control the separation angle of skyrmions.Additionally,we demonstrate control over the topological charge parameter to achieve symmetric and asymmetric HESSs.This effect not only enhances the manipulation capabilities of optical fields but also opens up potential applications for high precision displacement measurements and preservation quantum information.
