Abstract :
Spectral characteristics of multiple and cascaded phase-shifted fiber Bragg grating (FBG) are analyzed based on the coupled-mode theory with the transfer matrix method. It shows that multi-wavelength output (or comb filters) can be obtained by increasing the number of the phase shifts. The peak wavelength of the transmission band of the cascaded phase-shifted FBG will move towards long wavelength direction when compared with one FBG with multiple phase shifts, and the bandwidths become narrower.
