摘要： An optical waveguide device including a package housing having an element mounting surface, an element inserting groove opening to the element mounting surface, and a cutout as a space opening to an inner surface of the element inserting groove; and an optical waveguide element having a dielectric substrate, an optical waveguide formed in a surface of the dielectric substrate, and an electrode formed over the surface of the dielectric substrate, the optical waveguide element being inserted and fixed in the element inserting groove of the package housing by using an adhesive. The cutout opens also to the element mounting surface. In applying the adhesive to the bottom surface of the element inserting groove and inserting the optical waveguide element into the element inserting groove, the adhesive flows into the cutout and is prevented from flowing up to the element mounting surface. Further, a working space for application of the adhesive to the bottom surface of the element inserting groove can be ensured by the cutout.

摘要： An object of the invention is to provide a polarization scrambler wherein the polarization of linearly polarized signal light can be rotated to facilitate obtaining a minimum degree of polarization, and wherein scrambling operation is possible even if signal light of optional polarization states is input. Accordingly with the polarization scrambler, a polarization rotation section is provided on an input side on a chip on which is formed an optical waveguide, and a polarization scrambling section is provided on an output side. With the polarization rotation section, the polarization of linearly polarized signal light which is transmitted by the optical waveguide is rotated by means of an acousto-optic effect due to an elastic surface wave generated by an electrode, so as to become 45.degree. with respect to a vertical direction of the optical waveguide. With the polarization scrambling section, the polarization of the signal light from the polarization rotation section is scrambled in accordance with a modulation signal.

摘要： A wavelength selective optical switch of the present invention separates a WDM light emitted from an input port of an input and output optical system, according to wavelengths, by a diffraction grating, and thereafter, condenses the lights of respective wavelengths on MEMS mirrors respectively corresponding to the respective wavelengths, in a mirror array, to reflect them by a condenser optical system, to thereby switch optical paths for the respective lights. The condenser optical system is configured by combining a plurality of lenses whose focal distances are different from each other, and positions in an optical axis direction of the lenses are adjustable by a slide mechanism. Thus, despite an error in the focal distances of the condenser lenses, in a mounting angle of a spectral element or the like, a beam pitch at the condensing positions of the lights of respective wavelengths can be coincident with a mirror pitch in the mirror array.
