    Abstract: A first electro-optic crystal substrate and a second electro-optic crystal substrate are provided as an electro-optic crystal substrate. 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.

    Abstract: An optical switching element includes a resonant reflection element (11) and a driving unit (12, 14). The resonant reflection element (11) has a thickness portion functioning as a waveguide layer, with one surface in a thickness direction functioning as a total reflection surface and the other surface having formed thereon a fine periodic structure with fine asperities, the resonant reflection element resonant-reflecting light that is incident from the other surface and has a specific wavelength component. The driving unit (12, 14) varies a resonant wavelength of resonant refection by varying at least one of a shape and a refractive index of the resonant reflection element (11).
