均匀干涉场中的啁啾光纤光栅的成栅技术

The Technique Progress of Chirped Gratings Written in Fiber in Uniform Interfere Field

从改变有效折射率、光栅常数及同时改变有效折射率与光栅常数三个方面介绍啁啾光纤光栅成栅技术 。

Chirped fiber gratings have important applications in diffuse compensation of long distance and high velocity fiber communication systems. Signal compress, increase level and other. Methods of fabricating chirped fiber gratings are introduced. By changing effective refractive index, grating constant or changing effective refractive index and grating constant simultaneously, their characteristics and performance are also discussed.
