Abstract :
A novel all-fiber asymmetrical Sagnac loop interferometer is proposed to measure the chromatic dispersion of a multichannel fiber Bragg grating (FBG). This method has the advantages of simple configuration, low cost, and high tolerance for the characteristics of FBG as well as the ability to uniquely determinate the phase delay.
