【摘要】 采用火焰水解法 (FHD)在Si基上淀积SiO2 预制材料 ,然后在真空中 空气气氛中高温处理 (1 380℃ ) ,制得玻璃化的SiO2 膜材料 ;该材料膜厚适中 (1 0 30 μm)、平整度好、光滑透明 ,适合制作单模、多模列阵平面波导光栅。并利用XRD、SEM、台阶仪等仪器对SiO2 膜进行了测试分析。更多还原

【Abstract】 The SiO 2 films were deposited on silicon substrate by Flame Hydrolysis Deposition (FHD). Then ,the films were consolidated in electric furnaces at 1380℃ to make silica glass. The glass films(10 ~ 30μm thick) were uniform, glassy and transparent, which could be used to fabricate both single-mode and multi-mode arrayed waveguide grating. Finally, the silica films were analyzed by SEM, XRD, etc.更多还原
