Abstract

To widen the frequency tunable range of the Optoelectronic Oscillator（OEO）

a frequency tunable OEO based on a chirped Phase-Shifted（PS）is simulated and designed by the Matlab software.Firstly

the characteristics of the reflective spectrum of a common PS-FBG and the frequency tunable range of the OEO based on the common PS-FBG are theoretically and studied via simulation.Then

a method of transfer matrix is employed to analyze the reflective spectrum of the chirped PS-FBG and the tunable range of the OEO based on the chirped PS-FBG.The simulation results show that the tunability of frequency is achieved by tuning the wavelength of a tunable laser source.Compared with the common PS-FBG

the bandwidth of the chirped PS-FBG is increased so that the frequency tunable range of the optoelectronic oscillator is widened.
