| titleOfInvention | Second harmonic generation element and manufacturing method thereof |
| abstract | (57) Abstract: Propagation loss in an optical waveguide in a second harmonic generation device having an optical waveguide of a periodic domain inversion structure formed by a rubidium ion exchange method on a substrate of KTiOPO 4 single crystal. Decrease and increase the output of the second harmonic. A plurality of rubidium ion exchange regions 14A, 14B, 14C, 14D are formed on the surface of a substrate 10, and an optical waveguide 11 having a periodic domain inversion structure is formed by the rubidium ion exchange regions. The ratio of titanium to the stoichiometric composition ratio on the surface of the rubidium ion exchange region is 90% or more and 100% or less, The proportion of phosphorus is 80% or more and 100% or less, and the proportion of rubidium is 40% or more. The surface of the rubidium ion exchange region is polished to 4.0 μm or more and 6.0 μm or less. |
