摘要
相移光纤光栅可作为密集波分复用 (DWDM)系统中的解复用器 ,相移的大小、位置和相移点的多少对该解复用器的性能有重要影响。应用传输矩阵理论分析了相移光纤光栅的相移大小。
Phase shifted fiber Bragg grating(PSFBG) can be used as a optical wavelength demultiplexing for dens wavelength division multiplexing optical communication.The characteristic of optical wavelength demultiplexing was greatly influenced by the position and value of the phase shifts in PSFBG.The transmission spectrum of PSFBG was analyzed using a scattering matrix approach based on the couple mode theory.The computed results were obtained.
