Fabrication of Various Fiber Bragg Gratings Using the UV-Argon Laser

제2고조파 Argon Laser를 이용한 여러 가지 광섬유 격자의 제작

Fiber Bragg gratings have many applications such as fiber sensors, band-stop filters, add-drop filters, and mode convertors. In this paper, we present the fabrication method of various fiber Bragg gratings by using continuous wave UV-Argon(frequency-doubled Argon) laser. In our experiments, hydrogenation of fibers was used to enhance photosensitivity of fiber. And we fabricated fiber gratings by the phase mask method.
