Fabrication and Performance of Membrane in Arrayed Waveguide Grating
-
摘要: 以一種特定成分的有機硅為原料,采用溶膠-凝膠法,在硅基片上制備出用于光波導器件的薄膜.通過折射率和厚度測試及XPS成分測試驗證了此薄膜具有較好的均勻性、厚度和光學特性,滿足光波導器件的要求.分析了溶膠-凝膠法中常見的龜裂現象的原因以及采預防方法.利用這種薄膜結合微電子加工工藝制備出光波導器件陣列波導光柵.Abstract: Waveguide membrane on Si basement was fabricated by So-Gel method with a special kind of organic Si as raw material. After a serial of tests including thickness test, optical test and XPS test, it was concluded that this membrane was thick enough and has good quality. Since Sol-Gel method always causes chap and split, a method how to deal with it was discussed. Finally, how to fabricate an arrayed waveguide grating with the membrane was also introduced.
