| 摘 要： | 报道一个简单而新颖的、能将均匀光栅改变为线性啁啾光栅的方法，此方法可对光纤光栅的喃啾度和中心波长进行独立调节，实验表明，一长为１０ｃｍ的均匀光栅其啁啾度可增加至０．５ｎｍ／ｃｍ，而中心波长独立可调量达０．７ｎｍ利用这样的可调啁啾光栅在标准单模光纤（Ｇ６５２）中对一脉宽为２５ｐｓ的输入信号在１５５０ｎｍ窗口传输，成功地实现１００ｋｍ的色散补偿。 |

| Abstract: | A simple and novel method for transforming a uniform fiber grating into a linearly chirped grating is presented. This method permits independent tuning of the chirp degree and the central wavelength of the fiber gratings. It is demonstrated experimentally that the chirp degree of a 100 mm long uniform grating can be increased up to 0.5 nm/cm and its central wavelength can be independently tuned by 0.7 nm. A transmission experiment for compensating the dispersion of a standard single mode fiber (G652) over a distance of 100 km of a 25 ps input signal in the 1550 nm windows was successfully demonstrated using such a tunable chirped grating of 10 cm in length. |
