However, the exhaustive utilization of these intrinsicdegrees of freedom has saturated the parameter space for holographic encoding, leaving no room for furtherscalability. Here, we demonstrate an OAM multiplication operator enabled holographic multiplexing. We engineer theoperator-specific hologram that selectively responds to the predefined operator pathway. Subsequent validation oforthogonality between distinct operator pathways ensures the multiplexing ability, thereby enabling the parallelencoding of multiple holographic images. In the experiment, we have successfully demonstrated a ninefold capacityenhancement over conventional OAM holography and a 2-bit operator-multiplexed hologram for high-security opticalencryption. This work introduces operators as a synthetic dimension beyond light’s intrinsic properties intoholography, unlocking a scalable and secure paradigm for ultrahigh-dimensional information technologies.展开更多
