Vortex transitions on liquid crystal light valve

Optical vortex generation has attracted great interest in the scientific community due to its broad applicability in various technological developments. Several studies on optical vortex generation have been performed in liquid crystal media, specifically in transmission liquid crystal light valves; controlled and localized induction by light of optical vortex has been experimentally observed. An adequate amplitude equation, derived from first principles, describes this phenomenon. Theoretically, we find different localized vortex solutions depending on the bifurcation parameter. Experimentally, we analyze the transition point concerning voltage and intensity, proposing further investigation into these vortex-like solutions and their detailed characterization of structural transitions. The theoretical model of the liquid crystal light valve predicts several vortex structures that have not been studied experimentally. Based on a liquid crystal light valve experiment with applied light and voltage, we show the transition and appearance of different vortex structures. The study and detailed characterization of structures outside the limits predicted by the theory and possible corrections are proposed.
