The research progress and the facing difficulties of active / passive planar optical waveguides were systematically summarized and reviewed in this paper . zro2 - si02 binary oxide gel glasses and films applied for active optical waveguides were prepared by the sol - gel method with zirconium oxychloride and tetraethoxysilane as precursors . the paper has investigated the influence of the compositions of system and heat treatment temperature on the system refractive index in zroj - sioj binary oxide gel glasses 本文在系统综述有源和无源平面光波导材料研究进展、前景和面临的主要问题的基础上,应用溶胶?凝胶技术,以teos和zrocl _ 2 ? 8h _ 2o为先驱体,研制了用于有源光波导基质材料的zro _ 2 ? sio _ 2二元系统凝胶玻璃块材和薄膜。
