| titleOfInvention | Optical waveguide type second harmonic generator |
| abstract | (57) [Summary] [Object] An object of the present invention is to manufacture a device structure that more efficiently generates a second harmonic by using potassium titanate. [Structure] A region in which the direction of spontaneous polarization is periodically inverted on the Z plane of a potassium titanate single crystal substrate, and a ridge-type optical waveguide that guides a second harmonic to the region at right angles, Improve conversion efficiency. Alternatively, the same single crystal substrate Z A channel waveguide is produced in the direction of the period in a region where the spontaneous polarization is periodically inverted on the surface, and a ridge-shaped portion that guides the second harmonic is further provided on the channel waveguide to improve the conversion efficiency. .. |
