Achieving efficient and comprehensive control over all parameters ofcircularly polarized light (CPL) remains a significant challenge in advancedoptical applications, including information encryption, opticalcommunication, quantum computing, etc. Conventional CPL materialstypically combine luminescence and chirality in a single component for directCPL emission or rely on intrinsically chiral components to optically filterunpolarized light. However, these strategies limit design flexibility and hinderefficient tunability. This study addresses these limitations by introducing astructurally decoupled approach to CPL production. The proposed multilayercomposite system, composed entirely of achiral components, decoupleschirality from luminescence and intrinsic structural elements. Specifically,achiral fluorescent films are integrated with twist-stacked plasmonic polymernanocomposite layers, achieving a high dissymmetry factor of 0.3 in thevisible region. This innovative design allows independent control over CPLparameters, including wavelength, ellipticity, and handedness, throughmechanical rotation or deformation. The decoupled architecture significantlyenhances the material’s design flexibility, scalability, and environmentalstability. Furthermore, the resulting dynamic CPL material demonstratespractical applications in multi-level, high-capacity information encryption,offering promising prospects for advanced optical technologies.
