| Abstract: | At first, we systematically sum up and deduce the figure of merit of the compensator using linearly chirped fiber gratings. Secondly, we solve the Reccatti differential equation by the Runge Kutta method and calculate the reflectivity and dispersion of the linearly chirped fiber gratings to obtain the figure of merit numericallu.On the other hand, we also discuss the figure of merit under the circumstances of three kinds of coupling coefficients and compare them Finally, we present one kind of perfect design of the compensator using the Gauss coupling function, and simply discuss the method to realize the Gauss coupling function in the fabrication of linearly chirped fiber gratings in this paper. |
