    • A surface emitting semiconductor laser comprises a semiconductor substrate; a lamination structure including a lower multilayer film reflecting mirror, an active layer, and an upper multilayer film reflecting mirror formed on the semiconductor substrate; and an upper electrode and a lower electrode for supplying an electric power to the active layer. The upper multilayer film reflecting mirror has a refractive index having a two-dimensional periodic distribution within a lamination plane except a predetermined region in the lamination plane. A circular hole layer is formed above the active layer, and includes a plurality of circular holes arranged in a peripheral region surrounding the predetermined region in a two-dimensional periodic pattern, so that a multilayer film formed on the circular hole layer including an inside of the circular holes to constitute the upper multilayer film reflecting mirror forms the two-dimensional periodic distribution of the refractive index together with the circular hole layer.

    • An optical phase modulator includes a main Mach-Zehnder interferometer having first and second main optical waveguide path arms, whose initial phase difference in the used wavelength is π, a first sub Mach-Zehnder interferometer having first and second sub optical waveguide path arms that are formed in the first main optical waveguide path arm, whose initial phase difference in the used wavelength is 0, and a second sub Mach-Zehnder interferometer having third and fourth sub optical waveguide path arms that are formed in the second main optical waveguide path arm, and whose initial phase difference in the used wavelength is 0. Of each of the main optical waveguide path arms and the sub optical waveguide path arms, at least the portions where high-frequency electrodes are formed are constructed using semiconductor waveguide paths, and reduce the effects of frequency chirping caused by an orthogonal component due to light absorption in the semiconductor.
