摘要: A prism pair (103p) is employed as an optical deflecting element (103a). The prism pair (103p) is constructed by a slab waveguide (103b), and first and second upper electrodes (103c,103d) and first and second lower electrodes (103e,103f) arranged on and under the slab waveguide. These electrodes are shaped into a wedge shape (e.g., triangular shape), and change the refractive index of a part of the slab waveguide (103b) by utilizing the electrooptic effect to change the propagation direction of light.
A substrate comprises an integrated waveguide (211). A dielectric multi-layered film mirror (212) is arranged at the bending portion of the optical waveguide (211) to have an angle of 45 degree to the center line of the optical waveguide. The mirror (212) is formed by providing a plurality of mutually-parallel slits (205) in a part of the optical waveguide.摘要翻译: 使用棱镜对(103p)作为光学偏转元件(103a)。 棱镜对(103p)由平板波导(103b)和布置在平板波导上和下方的第一和第二上部电极(103c,103d)和第一和第二下部电极(103e,103f)构成。 这些电极被成形为楔形(例如,三角形),并且通过利用电光效应来改变平板波导(103b)的一部分的折射率以改变光的传播方向。 衬底包括集成波导(211)。 电介质多层膜反射镜(212)布置在光波导(211)的弯曲部分处,与光波导的中心线成45度角。 反射镜(212)通过在光波导的一部分中设置多个相互平行的狭缝(205)而形成。
