Abstract
An optical element has a structure in that a first mirror stack layer is formed on a substrate. A first transparent conductive film, a conductive buffer layer, a spacer layer having a primary or secondary electrooptic effect, a conductive buffer layer and a second transparent conductive film are stacked thereon in succession; and a second mirror stack layer is further formed thereon. A voltage is applied between the first and second transparent conductive films. The applied voltage change the refractive index of the spacer, changes a wavelength to be transmitted through or reflected from the layer.
