Optical waveguide device and method of manufacturing same |
摘要 |
A method of manufacturing an optical waveguide device that is capable of reducing the imbalance in the refractive index profile of a core, and an optical waveguide device that has the reduced imbalance in the refractive index profile are provided. The method of manufacturing an optical waveguide device has the steps of forming a groove in a first cladding layer having a first dopant that lowers the refractive index of the first cladding layer below the refractive index of pure silica glass, forming a core in the groove, and forming a second cladding layer having a second dopant that lowers the refractive index of the second cladding layer below the refractive index of pure silica glass, over the first cladding layer and the core.
