| Abstract: | By using the coupled-mode theory and transmit matrix,the spectral characteristics of phase-shifted long-period fiber gratings was analyzed.The difference between the index apodization and length apodization on the phase-shifted long-period fiber gratings were also discussed.The result shows that spectral caused by different apodized function is totally different in length apodization. |
