Bragg Grating Formation in B/Ge Codoped Optical Fibers
摘要
Abstract
A 2-cm long Bragg grating with reflectivity of ~99.95% in B/Ge codoped optical fiber without hydrogen loading was created by phase-mask method with a pulsed KrF excimer laser at 248 nm. DC and AC components of refractive index change were analyzed by monitoring transmission spectrum evolution during the writing process of fiber Bragg grating. The relations of the evolution of center wavelength and reflectivity with number of pulses were respectively investigated.
