The first electro-optic crystal substrate comprises a first periodic polarization reversal structure in which first polarization pairs, in each of which the directions of polarization in response to electric fields are opposite to each other, are arranged in a first period along a first arrangement direction which is orthogonal or inclined with respect to the direction of propagation, and light passes through the first periodic polarization reversal structure. The second electro-optic crystal substrate comprises a second periodic polarization reversal structure in which second polarization pairs, in each of which the directions of polarization in response to electric fields are opposite to each other, are arranged in a second period along a second arrangement direction which is orthogonal or inclined with respect to the direction of propagation, and light outstanding from the first electro-optic crystal substrate passes through the second periodic polarization reversal structure. At least one of a first condition and a second condition is satisfied. The first condition is that the first and the second periods are different from each other and a second condition is that the first arrangement direction and the second arrangement direction are different from each other.

摘要： A system for chromatic dispersion compensation is presented. The system includes an optical splitting element, a plurality of optical elements, and a plurality of waveguides. The optical splitting element is configured to generate at least a first beam of radiation and a second beam of radiation. The plurality of optical elements is configured to identify one or more optical paths amongst a plurality of optical paths for the first beam of radiation to travel. One of the plurality of waveguides disposed in one of the plurality of optical paths has group delay and dispersion coefficient properties per unit length that are different from group delay and dispersion coefficient properties per unit length of another one of the plurality of waveguides disposed in another one of the plurality of optical paths. The group delay and dispersion coefficient properties per unit length compensate for a chromatic dispersion associated with the second beam of radiation.

A magnetism-holding member of a high magnetic permeable material is preferably arranged at least in a part of an outer periphery of the coil. In case the Faraday element uses a magnetic garnet crystal having a residual magnetization, obtained is an optical rotator having a self-sustaining function. Such an optical rotator is utilizable for an optical switch.
