Theoretical Analysis of Long-Period Moiré Gratings

GAO Kan, ZHOU Ying-wu, QU Rong-hui, FANG Zhu-jie(Shanghai Institute of Optics and Fine Mechanics, The Chinese Academy of Sciences, Shanghai 201800, China)  
As a kind of band-rejected loss filter, long-period fibre gratings have wide applications in the field of fibre communication and fibre sensing. Combined with the transmission characteristics of long\|period fibre gratings, the transmission spectrums of various long-period moiré gratings were simulated by the method of transfer Matrix. The results of analysis indicate that the moiré gratings technology can be well applied in fabricating the high-performance phase-shifted and apodised long-period fibre gratings.
