论文摘要
集成的Kerr Microcombs是一种强大的工具，它是光子RF和微波信号处理的多个波长通道的来源，主要是在横向过滤器的背景下。他们提供紧凑的设备足迹，非常高的多功能性，大量的波长和宽的奈奎斯特频带。在这里，我们回顾了基于Kerr Microcomb的光子RF和微波重新配置过滤器的最新进展，这些过滤器既基于横向滤波器方法，又基于RF到光学带宽缩放。我们比较宽梳间距梳子（200GHz）与更细小的（49GHz）微型群的宽梳子间距（200GHz）进行了比较。还讨论了在功能和集成性方面，光学微型汤的强大潜力。
Integrated Kerr microcombs are emerging as a powerful tool as sources of multiple wavelength channels for photonic RF and microwave signal processing mainly in the context of transversal filters. They offer a compact device footprint, very high versatility, large numbers of wavelengths, and wide Nyquist bands. Here, we review recent progress on Kerr microcomb-based photonic RF and microwave reconfigurable filters, based both on transversal filter methods and on RF to optical bandwidth scaling. We compare and contrast results achieved with wide comb spacing combs (200GHz) with more finely spaced (49GHz) microcombs. The strong potential of optical micro-combs for RF photonics applications in terms of functions and integrability is also discussed.
