摘要
量子级联激光器(Quantum Cascade Laser,QCL)是依赖电子在量子阱子带间跃迁辐射出光子而发生激射的单极型半导体激光器。大量的理论与实验研究已经证明轻微的外部扰动(如光反馈、光注入)或内部足够强的非线性模式耦合能够引起半导体激光器的非线性输出。QCL作为新型半导体器件,具有腔内强度高、子带间光学非线性强以及电子弛豫时间快等特点,激发了学者研究其非线性动力学的兴趣。本文详细综述了QCL的非线性动态特性研究进展情况,探究了QCL非线性动力学性质的产生机理,总结了QCL非线性特性的应用场景。
Quantum Cascade Laser(QCL)is a unipolar semiconductor laser that relies on the excitation of photons radiated by electrons leaping between subbands of quantum wells.Numerous theoretical and experimental studies have demonstrated that slight external perturbations(optical feedback,optical injection)or sufficiently strong internal nonlinear mode couplings can induce nonlinear output of semiconductor lasers.QCL,as a new type of semiconductor device,is characterized by high intracavity strength,strong inter-subband optical nonlinearity and fast electron relaxation time,which has stimulated the interest in studying its nonlinear dynamics.In this paper,we review in detail the progress of the study of nonlinear dynamical characterization in QCL,explore the mechanism of the generation of nonlinear dynamical properties of QCL,and summarize the applications of nonlinear properties of QCL.
