| titleOfInvention | Optical waveguide type optical amplifier and manufacturing method thereof |
| abstract | (57) [Summary] [Purpose] The objective is to realize an optical waveguide type compact optical amplifier. [Structure] An optical waveguide doped with erbium is formed on a lithium tantalate crystal substrate or a lithium niobate substrate, and an input / output optical fiber is connected to this optical waveguide to form an optical amplifier. When pumping light is incident on the input optical fiber at the same time as the signal light, the signal light is amplified by the optical amplification effect of erbium, and the amplified signal light and pumping light from the output optical fiber are separated and amplified through the filter. Take out the signal light. As a method for producing an optical waveguide, liquid phase epitaxial is used, and by adding an amount of an element that replaces a part of the constituent elements of lithium niobate to the crystal raw material, a wavelength band for amplification with erbium having a light amplification effect is obtained. A lithium aluminum niobate crystal layer homogeneously doped with a high concentration of aluminum to be spread is epitaxially grown, and an optical waveguide is formed on the crystal layer by ion milling. |
