摘      要：The dynamic performance of an interband cascade laser (ICL) with optical injection is studied within the framework of rate equations. The effect of stage number m and active area A on the ICL optical injection-locking diagram is numerically simulated. ICLs with a small stage number and large active area have a relatively large phase-locked region. When the stage number is small, the system exhibits a large number of extreme pulses in the frequency-unlocked region. We show that step-down perturbations of the laser pump current can trigger and suppress extreme pulses by changing the parameters of amplitude, duration, and modulation time points. The amplitude and duration of current perturbation have a significant impact on the number of extreme pulses. This work provides different insight into the generation and control of extreme pulses based on ICLs.
