高带宽的载波相位和重复频率控制是构造低相位噪声光频梳的关键。在这里，我们演示了使用的石墨烯调制器为前者和散装电光调制器为后者，使记录低相位噪声操作的Er光纤频率梳。对于不需要载波相位控制的应用程序，我们表明，光纤梳的形状因子可以通过调整石墨烯调制器快速重复率控制来减少。此外，整个系统的演示与全保偏铒光纤频率梳，非常适合在现场的应用。
High bandwidth carrier phase and repetition rate control are critical for the construction of low phase noise optical frequency combs. Here we demonstrate the use of a graphene modulator for the former and a bulk electro-optic modulator for the latter enabling record low phase noise operation of an Er fiber frequency comb. For applications that do not require carrier phase control, we show that the form factor of a fiber comb can be reduced by adapting a graphene modulator for rapid repetition rate control. Moreover, the whole system demonstration is performed with all-polarization maintaining Er fiber frequency combs, highly suitable for applications in the field.
