| 深入探讨了量子级联激光器（Quantum Cascade Laser， QCL）中光频梳的工作机制，包括其产生光频梳的方式以及相关的非线性效应（如四波混频效应）对其运行的影响。阐述了QCL波导设计的重要性，分析了QCL光频梳在中红外和太赫兹波段的应用前景。指出可通过完善理论模型、对自启动谐波光频梳的物理机理进行理论解释等方式，提高光频梳的设计效率。展望了环形QCL在孤子通讯、光谱测量等领域的发展方向。 |
| 英文摘要: |
| In this paper, the mechanism of optical comb in Quantum Cascade Laser (QCL) are discussed, including the way of generating optical comb and the influence of related nonlinear effects (such as four?wave mixing effect) on its operation. The importance of waveguide design for quantum cascade laser is elaborated, and the application prospects of QCL optical frequency comb in mid?infrared and terahertz bands are analyzed. It is pointed out that the design efficiency of optical frequency comb can be increased by improving the theoretical model and explaining the physical mechanism of self?starting harmonic optical frequency comb. The development direction of loop quantum cascade lasers in soliton communication and spectral measurement is prospected. |
