Dynamic Holographic Display With Multiplexed Dielectric Metasurfaces.

With the increasing demand for tunable optical functionalities, metasurfaces capable of dynamic wave control have attracted growing attention. Compared with reconfigurable designs that rely on external stimuli, incident-light-modulated multiplexed metasurfaces offer a unique scalable pathway for achieving tunable functionalities. In this work, based on multiplexed metasurface schemes, we show hybrid multiplexing of polarization, wavelength, and orbital angular momentum (OAM) can be applied for dynamic tuning. We start to demonstrate a noise-engineered metasurface platform that supports dynamic holographic display across multi-nonorthogonal polarization channels, further combined with position, wavelength, and OAM multiplexing. Moreover, we extend this approach to achieve simultaneous multiplexing of polarization, wavelength, and OAM. This integration enables a single device to dynamically switch among holographic patterns under different incident light configurations, significantly enhancing the functional diversity of dynamic displays. Our strategy presents a highly compact and efficient solution for high-capacity multi-dimensional holography, with promising applications in advanced displays, data storage, optical encryption, and adaptive photonic systems.
