Abstract:Based on the coupled mode theory,the chirped Moire grating formed by tow linear chirped fiber gratings was analyzed in detail via the matrix approach.A deeper insight into the relationship among its reflectance spectrum,time delay and the grating parameters,such as the length of the chirped Moire grating,the chirp parameter and the peak refractive index modulation,was obtained.
Keywords:Wavelength  division  multiplexing  Chirped Moire fiber gratings  Matrix approach
