| 摘 要： | 光纤 Bragg光栅的饱和效应可引起二阶衍射,并使一阶衍射的峰值反射率下降.本文利用折射率变化模型和耦合模理论,模拟了饱和情况下 Bragg光栅的一阶和二阶衍射谱,并讨论了饱和系数对一阶和二阶衍射的 Bragg波长和峰值反射率的影响.数值模拟结果与参考文献中的实验结果相吻合.

| Abstract: | Saturation effect of fiber Bragg gratings can cause the second-order diffraction and the decreasing of the first-order maximum reflectivity.Using the model of index variation and mode-coupling theory,first and second-order diffraction spectra of fiber Bragg gratings after saturation are simulated.Bragg wavelength shifts and the changes of maximum reflectivity during the formation of fiber Bragg gratings versus the variation of saturation coefficient are also simulated.The simulation results are corresponding to the experimental results in references. |
