Paper Abstract
Phase-shifted chirped fiber Bragg grating (PS-CFBG) with dual π phase shifts was studied theoretically and designed by
classic transfer matrix approach. The transmission characteristics of the PS-CFBG with two transmission peaks are only
directly dependent on the position of dual π phase shifts. The linewidth of two peaks increase with the chirp rate of the
grating, and is not related with the wavelength difference of the peaks. A dual PS-CFBG was fabricated by ultraviolet
point-by-point scanning with a ~2.4 nm/cm chirped phase mask. Phase shifts were introduced by controlling half period
movement of grating accurately through the piezoelectric ceramic (PZT). The wavelength spacing, extinction ratio, and
3dB linewidth of two transmission peaks are 8nm, 20 dB and 0.08 nm, respectively, which agree with the theoretical
design.
