Abstract
Optoelectronics could be used to develop fast and wideband information systems. However, the large frequency mismatch between optically synthesized signals and electronic clocks makes it difficult to synchronize optoelectronic systems. We describe an on-chip microcomb that can synthesize single-frequency and wideband signals covering a broad frequency band (from megahertz to hundreds of gigahertz) and that can provide reference clocks for the electronics in the system. Our synchronization strategy, which aligns optically synthesized signals and electronics, can provide signal manipulation precision and data transmission without coherent digital signal processing. To illustrate the capabilities of this approach, we create a wireless joint sensing and communication system based on a shared microcomb-based transmitter.
