An effective approach for adjusting the Bragg wavelength of fiber grating

Abstract

An effective method for adjusting the Bragg wavelength of fiber grating is reported in this paper. For annealed fiber grating written on hydrogen loaded fiber, by UV uniform exposure, the Bragg wavelength can be adjusted effectively, and the reflectivity can be enhanced also. This method successfully solves the problem of Bragg wavelength controlling for fiber grating fabrication.Department of Electrical Engineerin
