Abstract
A method for manufacturing a nonlinear optical thin film of a silica glass system with sufficient nonlinear optical characteristics, in which a glass substrate is disposed within a vacuum deposition chamber and an electron beam is applied to a SiO —GeO -system glass placed on a hearth liner to form a SiO —GeO -system thin film on the surface of the substrate . In an application of this method, ions of argon, for example, are emitted from an ion source to produce dipoles in the deposited SiO —GeO -system thin film. By applying an electric field to the SiO —GeO -system thin film thus formed, the dipoles are oriented to let the thin film exhibit nonlinear optical characteristics.
