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.

摘要

本文为外腔半导体激光器（ECL）的设计提出了一种智能方法（模糊逻辑），以更好地抑制干扰。作为一种非线性光学系统，ECL输出频率很难通过常规方法来稳定。对于ECL稳定，首选模糊逻辑算法，该算法可以自动更新参数。模糊逻辑系统在运行过程中会突然拒绝非线性干扰，根据拒绝的干扰在线更改运行速度和PID增益。为了证明该方法的有效性，设计了模糊逻辑ECL稳定系统。结果证明了该方法的有效性和鲁棒性。
