| 摘 要： | 提出了一种特殊的取样光纤光栅：啁啾sinc取样光纤光栅.研究表明，对于均匀光纤光栅进行啁啾sinc取样，可以实现色散斜率补偿和获得精确的反射波长数控制;对啁啾光纤光栅进行啁啾sinc取样，则能够实现色散和色散斜率的同时补偿，并且可以进行精确的波长数控制及获得各信道一致的反射率.利用啁啾sinc取样光纤光栅，可以对各种传输光纤进行色散和色散斜率的补偿.

| Abstract: | A special kind of sampled fiber Bragg grating (FBG) was proposed and researched: chirped-sinc-sampled FBG. By chirping the sampling period of sinc-sampled FBG with uniform grating period, both the accurate number of reflective wavelength channels and chromatic dispersion slope compensation can be obtained. By chirping the sampling period of sinc-sampled FBG with chirped grating period, the number of wavelength channels we needed and compensate both the dispersion and dispersion slope can be controlled simultaneously. Meanwhile, nearly identical reflectivity in all wavelength channels is also obtained. By utilizing chirped-sinc-sampled FBG, both the dispersion and dispersion slope can be simultaneously compensated for various transmission fibers. |
