| description | A waveguide optical element includes a waveguide layer which is formed on a substrate, through which light propagates and which has an end face from which the propagation light becomes incident on the waveguide layer or emerges, a thin film formed on the end face of the waveguide layer, for increasing or decreasing a reflectance of light at end face, and control means having an electrode formed on a portion of the waveguide layer, for controlling a refractive index of the portion of the waveguide layer, which portion is in contact with the thin film. And its driving method is provided. |
