Abstract
In an optical element, a first mirror stack layer is formed on a substrate, and a spacer layer made of a paraelectric material having a secondary electrooptic effect is formed thereon through a first conductive thin film. Further, a second mirror stack layer is formed thereon through a second conductive thin film, and a coupling layer is formed thereon; thus, a basic structure of the optical element is formed. By changing a voltage to be applied between the first and second conductive thin films, it becomes possible to switch wavelengths of light to be transmitted through the optical element at a high speed.
