Paper Abstract

In this paper, a nano-polarization device based on two-photon polymerization reduction was designed and experimentally investigated. A broadband near-infrared (3-5 μ m) linear polarizer doped with metal particles was designed. Different from the fabrication methods of lithography and ion etching used in traditional metallic gratings or nanostructures, a two-photon absorption-based photo-reduction and photopolymerization process was adopted. The mixed solution composed by gold salt and photoresist is exposed by a femtosecend laser at a wavelength of 780 nm, at which the reduction reaction of the gold ions and the polymerization reaction of the resin are completed simultaneously, and thereby metal particles in the polymerized material can be obtained. The clusters of the reduced gold particles were observed by scanning electron microscopy, and the peak of gold was found in the energy dispersive X-ray spectrometer, which demonstrated the feasibility of the experiment and laid the foundation for the subsequent functional device fabrication.
