论文摘要
我们从理论上制定并在实验上证明了一种从光谱强度的单次测量中重建频率梳子的振幅，相位和相干性的全光学方法。我们的方法利用单个非线性纤维中宽的数百个GHz的不同信号组件之间的泵诱导的光谱短和长距离耦合利用合成频率晶格。当与超快速的信号转换技术结合使用时，这种方法具有在光谱阶段和外来光源的光谱阶段和相干性能中实时测量脉冲对脉冲变化的潜力。
We formulate theoretically and demonstrate experimentally an all-optical method for reconstruction of the amplitude, phase and coherence of frequency combs from a single-shot measurement of the spectral intensity. Our approach exploits synthetic frequency lattices with pump-induced spectral short- and long-range couplings between different signal components across a broad bandwidth of of hundreds GHz in a single nonlinear fiber. When combined with ultra-fast signal conversion techniques, this approach has the potential to provide real-time measurement of pulse-to-pulse variations in the spectral phase and coherence properties of exotic light sources.
