The transmission spectrum of the phase shifted and apodized long period fiber grating with different parameters is calculated and analyzed based on the fundamental matrix approach. The design method of phase shifted optimum is given, it uses the nonuniform phase shifted method to optimize the transmission spectrum of long period fiber grating. Compared with uniform phase shifted and apodized method, this method can effectively remove the sidelobes near the resonant wavelength. The calculation and analysis results show that it is a effective design method compared with the design method of apodized optimum.
