摘      要：Many methods have been suggested to reduce dispersion in optical fiber communication. Among these methods, chirped fiber grating (CFG) is a promising scheme. This paper describes a linearly chirped fiber grating with 95% reflectivity and 0.3 nm bandwidth written using a double exposure method with a uniform phase mask. The CFG resonant wavelength is 1554.5 nm and dispersion is 1700 ps/nm. Dispersion compensation in a 10-Gb/s optical transmission system has been demonstrated using this chirped fiber grating. The power penalty induced by the dispersion compensation after 180-km transmission is 1 dB. This is the first report describing dispersion compensation of 180 km at 10-Gb/s optical transmission now-return to zero (NRZ) system in China.
