A novel grating is proposed to produce multi-wavelength output with inscribing phase-shifted fiber Bragg grating (FBG) in polarization-maintaining fiber (PMF). The reflective spectrum of grating is analyzed by a transfer matrix method. The effects of grating parameters on property of the phase-shifted FBG in PMF are discussed. We find that optimistic phase-shifted FBG in PMF with high reflective peaks, narrow bandwidths and multi-wavelength is possible if the grating parameters are properly selected.
