摘　　要：相移光栅在光通信领域具有较高的应用价值,文中用传输矩阵法,详细分析了相移光栅中相移量,折射率调制深度,相移位置及光栅长度对相移光栅的影响,并结合相移光栅在DFB光纤激光器中的应用进行了分析。分析表明,实际制作DFB光纤激光器时,应根据实际应用场合,对相移光栅的相关参数进行设计,从而提高光纤激光器性能。The phase-shift grating is regarded as a factors affecting the phase-shift grating, considering critical component in optical communication. Some the applications of the phase-shift grating in DFB fiber laser, have been discussed and analyzed by using the transfer matrix method, which includes the phase-shift magnitude, amplitude of the refractive index modulation, the phase-shift position and the phase-shift grating length. The analysis shows these factors need to be considered comprehensively in the designing for the improvement of characteristics of the fiber laser.
