从耦合模方程出发 ,利用传输矩阵法 ,模拟研究了线性啁啾光纤光栅的反射谱特性 ,给出了反射谱的 3d B带宽、反射峰值、峰值波长处的色散和边带抑制率与啁啾量的关系曲线 ,并得到了啁啾量优化取值范围 .
Based on the coupled-mode equations, the transmission spectra of the linear chirped fiber gratings are studied by using the transfer matrix method. The 3dB bandwidth of reflection spectrum, the reflection peak, the dispersion at the peak wavelength and the suppression ratio of the sidebands to the chirp The relationship between the amount of curves and get the chirp optimization range.
