摘要
从理论上分析了超结构光纤光栅的滤波原理,将所研制的超结构光纤光栅滤波器应用于自发布里渊散射测量中,初步实现了自发布里渊散射信号与瑞利散射信号的有效分离及自发布里渊散射谱的测量,并给出了实验系统及实验结果,表明了该方案的可行性。
In view of filter principle of superstructure fiber bragg grating' theoretically analyzing, the superstructure fiber bragg grating filter has been used in the spectrum measurement of Brillouin scattering. The separation of spontaneous Brillouin scattering with Rayleigh scatering and the measurement of spontaneous Brillouin scatering in dispersion shifted fiber have been achieved. The experimental system and result are presented. The primary result confirms this configuration is feasible.
