摘要
In this paper, we propose an ultra narrow band fiber grating filter which is composed of two optical circulators and two fiber Bragg gratings (FBG). Through numerical simulation and experiment investigation, a narrow-band output spectrum with 1064 nm center wavelength and 0.017 nm bandwidth is obtained. It may find a certain application in the fields of free space optic communication, laser tuning and so on as we believe. © 2013 Elsevier GmbH. All rights reserved.
