Abstract
Efficient optical phase modulation is essential for information processing. The polarization response of metallic nanoparticles plays a key role in the formation of vector hologram. Commonly, Ag nanoparticles reduced by incoherent UV lamp tend to grow in isotropy, which is unsuitable for the formation of polarization hologram and the resultant multicolor holograms recording-readout in polarization channels. Here, the Ag nanoparticles storage with high polarization-sensitivity and anti-radiation interference are realized via bi-photonic irradiation from UV and visible lasers with participation of electron-acceptor. For the first time, the orthogonal polarization storage efficiency of the system is higher than that of the parallel mode. Color-tunable holographic reconstruction by polarization-multiplexing is achieved. This work provides a significant research strategy for stable, high-density data storage and advanced display.
