| 摘要 |
The present invention relates to an optical means, a method of using and manufacturing respectively optical means in the form of material or components that has/have a spatially varying chemical compositio n by virtue of diffusion of mobile substances (35) therein and temperature changes (36, 38, 42, 44) that enable the manufacture of optical material or components having spatially varying optical properties. The method is well suited for creating refractive index variatio ns in optical materials for the manufacture of optical waveguides or for creating periodic refractive index variations in different types of optical waveguides. |
