论文摘要
我们演示了基于集成的孤子晶体晶体源源的光子RF积分器。通过使用横向结构延迟输入RF信号并逐步延迟输入RF信号，可以离散地集成。 MicroComb源提供了多达81个波长，该波长可实现6.8 ns的较大积分时间窗口，以及时间分辨率的速度最快为84 ps。我们执行各种输入RF信号的信号集成，包括具有不同时间宽度的高斯脉冲，具有不同时间间隔的双重脉冲和平方波形。实验结果表明与理论一致。这些结果验证了我们基于微型尸体的集成器，作为具有高性能以及可能较低的成本和足迹的RF信号集成的竞争方法。
We demonstrate a photonic RF integrator based on an integrated soliton crystal microcomb source. By multicasting and progressively delaying the input RF signal using a transversal structure, the input RF signal is integrated discretely. Up to 81 wavelengths are provided by the microcomb source, which enable a large integration time window of 6.8 ns, together with a time resolution as fast as 84 ps. We perform signal integration of a diverse range of input RF signals including Gaussian pulses with varying time widths, dual pulses with varying time intervals and a square waveform. The experimental results show good agreement with theory. These results verify our microcomb-based integrator as a competitive approach for RF signal integration with high performance and potentially lower cost and footprint.
