Review on research and applications of optical frequency combs based on quantum cascade lasers
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 com-munication and spectral measurement is prospected.
