【Abstract】 It is analysed theoretically and numerically the dispersion of the linearly chirped fiber gratings with different coupling profiles. The numerical simulations of the fiber gratings with the different coupling profiles for dispersion compensation at 10Gb/s of standard optical fiber are given. The results show that the linearly chirp fiber gratings coupling profiles produce a great impact on their dispersion cancellation in long distance.更多还原
