Abstract

Nonlinear optical polymers show promising potential applications in photonics, for example, electro-optical devices. Poly (methyl methacrylate) (PMMA) is widely used in optical waveguides, integrated optics and optical fibers. However, PMMA has not been used for nonlinear optical waveguides since it has a low nonlinear refractive index. We successfully prepared chalcogenide amorphous nanoparticles doped PMMA that had a high nonlinearity. The As₃S₇ bulk glass was dissolved in propylamine to form a cluster solution. Then the As3S7/propylamine solution was added into methyl methacrylate (MMA) containing photoinitiator Irgacure 184 about 0.5 wt%. After well mixing the As₃S₇ nanoparticle doped MMA was transparent. Under the irradiation by a 365 nm UV lamp, As₃S₇ nanoparticles doped PMMA was obtained with yellow color. The third-order nonlinear optical susceptibility of As₃S₇ nanoparticles doped PMMA was investigated. An optical waveguide array based on the As₃S₇ nanoparticles doped PMMA composite of high nonlinearity was fabricated.
