【Abstract】 The output power fluctuations among different wavelengths commonly exist in multiwavelength laser based on a semiconductor optical amplifier (SOA).Theoretical investigation on fiber grating(FG) comb filter for optical power equalization is presented in this paper.The FG parameters and its design method are also given.The simulation results indicate that the output power fluctuations are greatly suppressed compared with free oscillation laser spectra.更多还原
