Title:
【発明の名称】光誘起ブラッグ格子の形成方法
Document Type and Number:
Japanese Patent JP3371048
Kind Code:
B2
Abstract:
In accordance with the invention, the index of refraction of a region (26) of a glass body (22) is selectively increased by treating the material with hydrogen and then simultaneously applying heat and actinic radiation to the region. Preferably the body is heated to a temperature in excess of 150 DEG C and the heat (25) and radiation are simultaneously applied. The result is a substantial and long-lived increase in excess of 5x10<-><5> in the refractive index of the irradiated region. This process can be used to make and adjust a variety of optical waveguide devices such as photoinduced Bragg gratings.
