Optical Faraday manipulating longitudinal component of optical vortex beams

Abstract

In this study, we aim to investigate the novel application of the Optical Faraday effect in manipulating the longitudinal component of optical vortex beams, which are characterized by their unique orbital angular momentum and helical phase structure. The Optical Faraday effect, induced by the interaction of a magnetic field with a specific optical crystal, results in a rotation of the polarization plane of light. This phenomenon is harnessed to exert precise control over the longitudinal component of optical vortex beams, a feature not typically present in conventional light beams. Our theoretical analysis explores the modulation of the longitudinal component, revealing a significant influence on the beam’s polarization characteristics, intensity distribution, and phase characteristics. This manipulation breaks new grounds for increasing the precision of optical systems, with potential applications in advanced optical communication, high-density data storage, and quantum information processing. The findings show that by finely tuning the magnetic field and material properties, it is possible to achieve a new kind of control mechanism over the propagation and interaction of optical vortex beams. This work paves the way for further exploration into the dynamic control of structured light, offering promising prospects for future photonic technologies.
