| dc.description.abstractEn | We report on the realization of on-demand reconfigurable arbitrary arrays of microscopic optical vortex generators in chiral liquid crystals. These generators are optically inscribed in frustrated cholesteric films by means of the laser-induced local winding of the chiral liquid crystal mesophase. This leads to the storage of microscopic, metastable, topological defect structures endowed with space-variant birefringent properties. Such structures are shown to produce optical vortices with a well-defined orbital state as a result of a spin-to-orbital angular momentum conversion process. | |
