摘　　要：提出了一种新的光纤光栅综合技术,将光纤光栅的传输矩阵法与粒子群优化算法(PSO)结合起来,得到了一种光纤光栅综合问题的全新方法。通过调整粒子群优化算法的相关参数,我们可以得到适合需要的反射谱。与其它光栅综合算法相比,该方法具有简单,收敛速度快等优点,同时该技术具有普遍性,还可以用于其它类似的综合问题。A new method lot synthesis of fitter gratings is proposed. By combining the transmission matrix method and the particles swarm optimization algorithm, we obtain a novel method for the inverse problem of the synthesis of fitter gratings. With the adjust of the parameters of the PSO algorithm we can get the demand reflection spectrum. Compare with other synthesis methods, the PSO Algorithm characteristics are simple and faster convergence, In addition the method is general, and would thus be useful for other inverse problems.
