量子级联激光器非线性动态特性研究进展
Progress in the study of nonlinear dynamic characteristics based on quantum cascade lasers
摘要
Abstract
Quantum Cascade Laser(QCL)is a unipolar semiconductor laser that relies on the excitation of photons radi-ated by electrons leaping between subbands of quantum wells.Numerous theoretical and experimental studies have dem-onstrated 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 dynami-cal properties of QCL,and summarize the applications of nonlinear properties of QCL.关键词
