An azo-functionalized copolymer derived from Poly (CACzE-MMA), CACzE, and DPP in is introduced as an innovative material to address challenges in vectorial holography. This copolymer surpasses existing materials by achieving a maximum diffraction efficiency of 85%, retaining holographic information for over 30 days, and allowing for fast writing at low intensity. By utilizing the copolymer's re-writability, polarization-angular multiplexing, and hybrid polarization-spatial multiplexing techniques are successfully implemented, which enables recording multiple images without significant crosstalk. This advancement has significant implications for holographic technology, expanding its applications in data storage, imaging, and display systems.
