摘要:
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-xO3 is used as an optical waveguide. The input optical signal is transmitted to the KTaxNb1-xO3 film. The KTaxNb1-xO3 film undergoes changes in optical property when an external voltage signal is applied to the electrode. Therefore, as it passes through the KTaxNb1-xO3 film, the input optical signal is modulated by the characteristic change. The modulated optical signal is taken out as an output optical signal.

提供了能够具有各种特性的光波导及其制造方法以及制造晶体膜的方法。 光学功能材料KTaxNb1-xO3用作光波导。 输入光信号传输到KTaxNb1-xO3胶片。 当向电极施加外部电压信号时,KTaxNb1-xO3膜经历光学特性的变化。 因此,当通过KTaxNb1-xO3胶片时,输入光信号由特征变化调制。 将调制的光信号作为输出光信号取出。
