摘要:
An optical waveguide (11) and a first lens (12) are formed on an underlying surface (10). The optical waveguide (11) guides light along a first direction (x). The first lens (12) is continuous with one end of the waveguide (11) and converges light radiated from the end plane of the optical waveguide (11) and diverging along directions parallel to the underlying surface (10). A second lens (25) converges light transmitted through the first lens (12) and diverging along directions perpendicular to the underlying surface (10). A support member (28) supports the first and second lenses (12, 25). It is possible to prevent a shift of positions of the optical waveguide (11) and lens (12, 25) by a temperature change and to prevent a light coupling efficiency from being lowered.
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.
