Latest Patents

Teppei Yanagawa holds a patent for a waveguide type optical element. This invention aims to effectively prevent the acceleration of the drift phenomenon generated by the application of a high electric field to a substrate through a bias electrode. The design includes a substrate with an electro-optic effect, two optical waveguides, a non-conductive layer made of materials with a lower dielectric constant than the substrate, and a control electrode. The control electrode generates a refractive index difference between the two optical waveguides by applying electric fields to them. The non-conductive layer consists of silicon oxide, an oxide of indium, and an oxide of titanium, with a specific molar concentration ratio. A voltage generating an electric field of 1 V/μm or more is applied to the control electrode.
