非线性光学聚合物在光电器件等光子学领域具有广阔的应用前景。聚甲基丙烯酸甲酯（PMMA）广泛应用于光波导、集成光学和光纤。然而，PMMA还没有用于非线性光波导，因为它具有低的非线性折射率。我们成功地制备了具有高非线性的硫系非晶纳米粒子掺杂PMMA。将As 3S 7块体玻璃溶解在丙胺中以形成团簇溶液。然后将As 3S 7/丙胺溶液加入到含有约0.5重量%的光引发剂Irgacure 184的甲基丙烯酸甲酯（MMA）中。在充分混合之后，掺杂MMA的As 3S 7纳米颗粒是透明的。在365 nm紫外灯照射下，得到黄色的As 3S 7掺杂PMMA纳米粒子。研究了As 3S 7纳米粒子掺杂PMMA的三阶非线性光学系数。制备了一种基于As 3S 7纳米颗粒掺杂的高非线性PMMA复合材料的光波导阵列。
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.
