| 摘 要： | 提出了一种均匀光栅辅助的光纤谐振环滤波器,利用传输矩阵法,推导了该器件的反射输出、精细度和全宽半高的表达式,并进行了数值计算.结果发现该器件的反射谱具有相移光栅反射谱的特点,并且该器件反射谱中透射窗口的位置和深度还具有可调谐性.最后,分析了谐振环参数对该器件反射谱的精细度和全宽半高的影响.

| Abstract: | A novel filtering device with Bragg grating-assisted cross-coupling fiber resonator is proposed.Us-ing the method of transmission matrix,analytical expressions of reflectivity and its finesse,full width at half maximum are derived.Computation results show that reflection spectrum of proposed device is similar to that of phase-shift grating.Location and depth of transmission window are tunability in its reflection spectrum.At last,influence on its finesse and full width at half maximum by the parameters of f... |
