Abstract

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.
