SYSTEM AND METHOD FOR FABRICATING BRAGG GRATINGS

摘要

A novel method based on sequential writing for fabricating of advanced fiber Bragg gratings is disclosed. As opposed to already presented sequential methods, this scheme uses a continuous wave UV laser source and allows for a very precise control and repetitively of the formation of the gratings. Furthermore, one can use high average irradiances without destroying the fiber, resulting in a dramatical shortening of fabricating times for complex gratings.
