摘要
PURPOSE: A method for fabricating a non-linear optical silica thin film is provided to irradiate polar particles during formation of the thin film and thereby polarization orientate the thin film. CONSTITUTION: The method comprises the steps of forming a non-linear optical silica thin film under radiation of polar particles and polarization orientating the optical silica thin film. The formation of the non-linear optical silica thin film is repeated under radiation of neutral particles or non-radiation to form a plurality of areas with different substrate orientations in the thickness direction of the silica thin film. The non-linear optical silica thin film comprises GiO2-GeO2 as a principal component.
