Spectral characteristics of chirped fiber Bragg gratings in large-mode-area fibers
摘要
Abstract
A matrix method is extended to solve the multimode coupling differential equations,and thereby the spectral characteristics of the chirped Bragg gratings in large-mode-area fibers (LMA FBGs) are studied theoretically.Unlike those of Bragg gratings in single mode optical fibers (SM FBGs),the reflection spectra of chirped LMA FBGs contain self-coupling and co-coupling peaks of the existing modes.For the chirped LMA FBGa,the reflectivity decreases and the reflection peaks split.These splits can be improved on some degree by Gaussian apodization function.关键词
