分析ＣｈｉｒｐｅｄＢｒａｇｇ光纤光栅的色散特性，并作一定性分析．利用耦合模方程导出ＣｈｉｒｐｅｄＢｒａｇｇ光纤光栅的反射率方程，从而推导出ＣｈｉｒｐｅｄＢｒａｇｇ光纤光栅的色散计算公式，并用数值分析画出它们的响应曲线．

An overall and qualitative analysis of the dispersion characteristic of Chirped Bragg fiber grating is given. Using the coupled mode equation, the reflectivity equation on Chirped Bragg grating and the formula to calculate the dispersion of chirped Bragg fiber grating are derived. The response curves with numerical analysis is obtained. The concept in figure of merit of microwave field to quantitize the compensational capacity of the dispersion compensation is introduced. An estimate of the compensation capacity of the unchirped or Chirped fiber gratings is made.
