摘要：Microcombs – optical frequency combs (OFCs) derived from integrated micro-cavity resonators – are cogent sources of numerous frequency channels which could be used for optical ultra-fast signal processing, as microcombs provide remarkable benefits staring high multifunctionality, a brief platform footprint, unprecedented figures of comb lines, as well as extensive Nyquist bandwidths. They have capacitated revolutionary breakthroughs in applications such as radio frequency (RF) photonics, spectroscopy, frequency synthesis technique, optical automatic ranging system, quantum source, metrology, and superhigh capacity optical data transmission. Photonic ultra-fast signal processing has been expected promising solutions to exceed the intrinsic bandwidth boundaries as their electronic counterparts. Over the past few years, optical techniques were introduced to boost the performance of RF systems, OFCs were then found to be the powerful tools in RF applications. There is a wide range of sorts of OFC sources that can offer large Nyquist bands, consistent channel power, and extensive comb lines. However, such approaches face the limitation of bulky set-up and a limited number of wavelengths, microcombs, therefore, stand out as a likely OFC source for ultra-fast signal processing systems.
