The frequency fluctuation characteristics of fiber grating lasers (FGL) with a single fiber Bragg grating (FBG) was investigated using an all-fiber unbalanced-arm scanning Michelson interferometer. A possible stabilization scheme was demonstrated using the error signal generated by the pseudo-heterodyne detection method. An improvement in the frequency fluctuation from ∓480 MHz to ∓30 MHz was demonstrated experimentally. The proposed scheme was found to avoid the problem of frequency dithering making it suitable for different dense wavelength division multiplexing (DWDM) network applications.
