| 摘 要： | 比较了光纤布拉格光栅法布里一珀罗腔的极限法、平衡法及传输矩阵法3种算法,证明了它们是一致的,指出了光纤布拉格光栅复振幅传输矩阵的相移特性对法布里一珀罗腔透射率的影响.对计算任意折射率调制的光纤布拉格光栅的Rouard算法进行了改进,在分层方法中考虑了折射率分布初始相位的影响,获得了更为准确的反射复振幅相位特性,将该结果应用于计算光纤布拉格光栅法布里一珀罗腔,得到了光纤布拉格光栅法布里一珀罗腔具有多峰结构的透射谱,并经过实验验证了该理论的正确性.

| Abstract: | The limit method, balance method and transfer matrix method for fiber Bragg grating (FBG) Fabry-Pérot (F-P) cavity are studied and proved uniform. The influence of the reflection phase of fiber Bragg grating complex amplitude transfer matrix on the transmission of fiber Bragg grating Fabry-Pérot cavity is emphasized. The Rouard method, which is capable of calculating fiber Bragg grating with arbitrary refractive index modulation, is used to calculate fiber Bragg grating Fabry-Pérot cavity and modified by introducing initial phase of refractive index distribution to calculate the reflection phase precisely. The transmission spectrum of fiber Bragg grating Fabry-Pérot cavity with multi-peak structure is obtained with the above results and the calculation results are proved by experiments. |
