Abstract
Metasurfaces with compact footprint and large information capacity bring unprecedented possibilities for the miniaturized optoelectronic systems. With the further exploration of intriguing wavefront tailoring possibilities, multiple dimensional multiplexing and dynamic modulation techniques combined with metasurface designs gradually become crucial research trends. Here, we utilize resonance effects and geometric phase of metasurfaces to simultaneously shape the amplitude, phase and polarization of light, and rebuild a vectorial holography with customized patterns and polarizations. By selecting the desired polarization combination continuously, dynamic display of vectorial meta-holography with 4-fold degeneracy is demonstrated. Such a method can precisely modulate the spatial phase and polarization distributions simultaneously at each frame, while the dynamic tunability is easy to implement based on polarization rotation. Such versatile and compact metasurfaces may provide promising solutions to dynamic and near-eye display, compact LiDAR, optical encryption, and date storage.
