Excimer Laser Application: Writing of Fiber Bragg Gratings

摘要

During the last decade the development of fiber Bragg gratings (FBG) was forced by the ever growing demand on data transmission capacity. Fiber Bragg gratings support as filters, amplifiers, and stabilizers the entire optical network philosophy avoiding optical to electrical signal conversion. Whereas in the early 1990s the most gratings were manufactured by researchers with continuous wave (cw) laser sources, the excimer laser became a common tool for high throughput writing of Bragg gratings in the mid 1990s . The excimer laser is nowadays still the most efficient UV laser source which leads to low cost of operations compared to other UV sources. This paper presents the possibilities and advantages of excimer lasers in regards to writing of fiber Bragg gratings.
