Abstract
Official abstract text for this publication.
An optical control element which has a thin plate having an electro-optical effect and a thickness of 10 μm or less, optical waveguides formed in the thin plate, and a plurality of optical control portions for controlling light propagating through the optical waveguide, wherein, a portion between a plurality of optical control portions is connected by a control signal wiring line that includes any one of a coplanar waveguide type disposed only on a surface of the thin plate, a coplanar waveguide type disposed on the surface of the thin plate and a ground electrode disposed on a back surface thereof, or a micro strip line, for arrival times of light and electric signal set to be substantially the same.
First claim
Opening claim text (preview).
What is claimed is: 1. An optical control element which has a thin plate having an electro-optical effect and a thickness of 10 μm or less, an optical waveguide formed in the thin plate, and a plurality of optical control portions for controlling light propagating through the optical waveguide, wherein the thin plate is any one of LiNbO 3 crystal, LiTaO 3 crystal, or solid solution crystals of both, wherein at least two or more of the plurality of optical control portions are…
