摘要

摘要本文提出了一种基于模糊逻辑的智能外腔半导体激光器设计方法，以获得更好的抗干扰性。ECL作为一种非线性光学系统，其输出频率难以用常规方法稳定。模糊逻辑算法具有自动更新参数的功能，适合于ecl的稳定。对模糊逻辑系统运行过程中可能出现的非线性扰动进行突发性抑制，根据扰动在线改变运行速度和PID增益进行抑制。为了验证该方法的有效性，设计了一个模糊逻辑ECL镇定系统。实验结果证明了该方法的有效性和鲁棒性。

Fuzzy logic based feedback control system for the frequency stabilization of external-cavity semiconductor lasers

Abstract This paper proposes an intelligent approach (fuzzy logic) for the design of external-cavity semiconductor lasers (ECLs) for better disturbance rejection. As a kind of nonlinear optical system, ECL output frequency is difficult to be stabilized by conventional methods. The fuzzy logic algorithm is preferred for ECLs stabilization, which could update parameters automatically. Suddenability to reject nonlinear disturbances arch occur in the fuzzy logic systemduring operation, speed of operation and PID gains are alteredonline in accordance with the disturbances to reject. To showthe efficacy of the proposed method, a fuzzy logic ECL stabilization system is designed. The results prove that our method is effective and robust.
