【発明の名称】集積光導波路とその製造方法、および集積光導波路を用いた電気光学変調器
Document Type and Number:
Japanese Patent JP2655678
Kind Code:
B2
Abstract:
Disclosed is an integrated optical waveguide. This integrated optical waveguide is obtained by doping a lithium niobate monocrystal simultaneously or in two stages, by a titanium strip, in a manner known per se, to obtain a guiding zone for the optical wave, and by a titanium film of smaller thickness which covers the guiding zone and the lateral zones to preserve a waveguide in the guiding zone and improve the electro-optical behavior of the guide to which an electrical field is applied.
