We experimentally and theoretically demonstrate the variety of the nonlinear dynamics exhibited by a single frequency semiconductor laser subjected to optical injection from a frequency comb. The injection parameters (the detuning and the injection strength) and the comb properties (comb spacing and the amplitude of the injected comb lines) are varied to unveil several dynamics such as injection locking, wave-mixing, chaotic dynamics, and unlocked time-periodic dynamics corresponding to new comb solutions. The asymmetry of the injected comb is shown to modify the size of the injection locking region in the parameter space, as well as the common properties between the new comb solutions observed and the injected comb.
我们通过实验和理论证明了单频半导体激光器在受到频率梳光注入时所展现出的各种非线性动力学特性。改变注入参数（失谐量和注入强度）以及频率梳特性（梳齿间距和注入梳齿线的幅度），以揭示诸如注入锁定、波混频、混沌动力学以及与新的频率梳解相对应的非锁定时间周期动力学等多种动力学现象。结果表明，注入频率梳的不对称性会改变参数空间中注入锁定区域的大小，以及所观察到的新频率梳解与注入频率梳之间的共同特性。
