| 摘 要： | 根据线性ChirpedBragg光纤光栅的一般原理 ,探讨了不同啁啾系数 ,准高斯耦合函数对Bragg反射光栅的反射率及色散补偿特性的响应。结果表明 :增大啁啾系数以及选取适当的准高斯耦合函数 ,在保证反射率较大的情况下 ,能有效地改善色散补偿特性。通过引入微波领域的“优化指数”这一概念 ,量化了色散补偿器的补偿能力。

| Abstract: | Based on the general theory of linearly chirped fiber Bragg grating, some parametres including different chirp values and quasi gauss coupling function relating with the reflectivity coefficient dispersion compensation were analysed. The result showed that selecting larger chirp and appreciate qusi guass coupling function could improve the dispersion compensation while ensuring the reflectiveity high. And we introduce the concept of “figure of merit” in the microware field to quantize the equalizing power of the dispersion compensator. |
