    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 multiaxial optical coupler for use in a device using an LiNbO3 substrate, which is reliable over a wide temperature range and capable of reducing coupling loss. A capillary has a plurality of linear through holes formed therethrough in a manner each inclined with respect to the central axis of the capillary such that the extension line of the central axis of the linear through hole extends through the center of a lens. A plurality of optical fibers are inserted into the linear through holes, respectively. This construction enables the optical axis of an optical beam emitted from each of the optical fibers within the capillary to pass through the center of the lens and reach the end face of a corresponding one of the optical waveguides. Similarly, the construction enables the optical axis of an optical beam emitted from the end face of each of the optical waveguides on the substrate to pass through the center of the lens and reach a corresponding one of the optical fibers within the capillary. The central axis of each of the linear guide holes is slightly inclined with respect to the optical axis of the lens. However, this inclination angle causes very little optical coupling loss.
