In a region in the vicinity of contact surfaces of the semiconductor layers 8 and 9 with the dielectric film 11, a free carrier is accumulated, removed, or inverted by an electrical signal from the external terminal, and whereby a concentration of the free carrier in an electric field region of an optical signal is modulated, so that a phase of the optical signal can be modulated. At least one of the semiconductor layers 8 and 9 is wider than the stacked portion. At least one of the highly-doped portions 4 and 10 is formed outside the stacked portion.

    Abstract: A one-dimensional photonic crystal has a spatial distribution in which the refractive index periodically varies in a first direction that light is caused to be propagated and in which the refractive index is uniform in a second direction perpendicular to the first direction. An antireflective coating structure for the one-dimensional photonic crystal includes a thin-film having a refractive index and a thickness determined by a predetermined calculation method. A two or three-dimensional photonic crystal comprises two or more media that have different refractive indexes and are arranged in a two or three-dimensional pattern. An antireflective coating structure for the two or three-dimensional photonic crystal includes a thin-film comprising one of the media included in the photonic crystal. In the structure, the thin-film is disposed on an end face of the photonic crystal so as to increase the incident efficiency of light entering the photonic crystal. Thereby, the reflection of the photonic crystal is securely prevented in a simple manner.
