A combination of acrylate formulations and SiO nanoparticles is investigated with the aim to improve the optical properties of low-refractive index polymers that are used for the fabrication of planar optical waveguides. A decrease in refractive index and also in the thermo-optic coefficient of nanocomposite materials is clearly demonstrated, while some formulations exhibit an increase in the glass transition temperature. The possibility of using these nanocomposite materials to fabricate waveguiding layers with low optical propagation losses at telecommunication wavelengths around 1550 nm is also shown. The nanomaterials can be applied in optical microchips on polymer platforms.
为了改善用于制造平面光波导的低折射率聚合物的光学性能，对丙烯酸酯配方和SiO纳米颗粒的组合进行了研究。纳米复合材料的折射率以及热光系数明显降低，而一些配方的玻璃化转变温度有所升高。还展示了使用这些纳米复合材料制造在1550nm左右电信波长处具有低光学传播损耗的波导层的可能性。这些纳米材料可应用于聚合物平台上的光学微芯片。
