| 摘 要： | 使用微波网络模型对光在光栅中的传播过程进行建模,给出了在光栅微波网络模型中的光场传输矩阵,并阐明了这种传输矩阵与传统分段光栅模型中的传输矩阵的关系;结合改进的有效折射率分析方法,提出了一种计算光纤光栅谱特性的新方法.该方法对应的MT矩阵很简洁且数值模拟的精度很高.

| Abstract: | The conceptions in microwave engineering are used to modeling the light transmission process in fiber Bragg gratings, yielding the corresponding transfer matrix in the microwave network grating model. The relationship of this novel transfer matrix and the traditional transfer matrix in piecewise uniform grating model is clarified. Combining the modified effective index method, a novel method for calculating the complex reflection spectrum is proposed. The MT matrix in this method is concise and a good exactitude of this method is confirmed by numerical simulation. |
