ABSTRACT:
An optical waveguide capable of having various characteristics and a method of manufacture thereof as well as a method of manufacturing a crystal film are provided. An optical functional material KTaxNb1−xO3is used as an optical waveguide. The input optical signal is transmitted to the KTaxNb1−xO3film. The KTaxNb1−xO3film undergoes changes in optical property when an external voltage signal is applied to the electrode. Therefore, as it passes through the KTaxNb1−xO3film, the input optical signal is modulated by the characteristic change. The modulated optical signal is taken out as an output optical signal.
