论文摘要
我们提出并证明了基于集成的KERR光学微型炸弹的可重构分数微波信号处理。我们达到了两种形式的微波信号处理函数，分数希尔伯特变换以及分数差异化。对于希尔伯特变换，我们证明了45度的相移，一半的希尔伯特变换的一半，而对于差异化，我们实现了平方根的分化。对于这两个方面，我们在17 GHz的宽带宽度上实现了高分辨率，而所达到的通过带的相位偏差小于5。在频率和时间域中的这种性能都证明了微型机器的多功能性和功率，作为高性能微波信号处理的基础。
We propose and demonstrate reconfigurable fractional microwave signal processing based on an integrated Kerr optical microcomb. We achieve two forms of microwave signal processing functions, a fractional Hilbert transform as well as a fractional differentiator. For the Hilbert transform we demonstrate a phase shift of 45 degrees, half that of a full Hilbert transform, while for the differentiator we achieve square-root differentiation. For both, we achieve high resolution over a broad bandwidth of 17 GHz with a phase deviation of less than 5 per degree within the achieved passband. This performance in both the frequency and time domains demonstrates the versatility and power of micro-combs as a basis for high performance microwave signal processing.
