The manipulation of a supercontinuum via delayed optical feedback is investigated experimentally. The supercontinuum is generated in a microstructured fiber and a feedback ring resonator introduces the optical feedback and leads to the formation of different regimes of nonlinear dynamics. Via the feedback phase the optical spectrum and the regimes of nonlinear dynamics can be adjusted systematically. The impact of delay detuning on two different length scales, namely on a sub-wavelength scale and on a larger scale in the order of 10 μm are discussed. Additionally, the adjustment of the optical spectrum without changing the regime of nonlinear dynamics is demonstrated.
通过延迟光反馈对超连续谱进行操控的实验研究。超连续谱在微结构光纤中产生，反馈环形谐振器引入光反馈并导致不同非线性动力学状态的形成。通过反馈相位，可以系统地调节光谱和非线性动力学状态。讨论了延迟失谐在两个不同长度尺度上的影响，即在亚波长尺度和大约10μm的较大尺度上的影响。此外，还展示了在不改变非线性动力学状态的情况下对光谱进行调节。
