除了克尔梳的放大之外，还实现了光学注入锁定，以忠实地传递耗散克尔微谐振器孤子梳的相位噪声。与掺铒光纤和半导体光放大器不同，光注入锁定可放大梳状模式，而不会降低光信噪比。此外，我们还表明，光学注入锁定的残余相位噪声足够小，足以传递低相位噪声克尔梳的梳模式的相对相位噪声（相当于重复频率），得出结论，克尔梳的光学注入锁定可以是通过克尔梳的光电转换产生具有高信噪比的低相位噪声太赫兹（THz）波的有效方法。 (c) 2021 年 Optica 出版集团根据 Optica 开放获取出版协议的条款
Optical injection locking is implemented to faithfully transfer the phase noise of a dissipative Kerr microresonator soliton comb in addition to the amplification of the Kerr comb. Unlike Er-doped fiber and semiconductor optical amplifiers, the optical injection locking amplifies the comb mode without degrading the optical signal-to-noise ratio. In addition, we show that the residual phase noise of the optical injection locking is sufficiently small to transfer the relative phase noise of comb modes (equivalent to the repetition frequency) of low phase noise Kerr combs, concluding that the optical injection locking of a Kerr comb can be an effective way to generate low phase noise terahertz (THz) waves with a high signal-to-noise ratio through an optical-to-electronic conversion of the Kerr comb.
