Chang Lin's team from the School of Electronics at Peking University has made significant progress in the field of photonic chip clocks
The research team of Chang Lin from the School of Electronics and the research team of Li Wangzhe from the Institute of Space Information, Chinese Academy of Sciences, published a research article titled "Microcomb-synchronized optoelectronics" online in Nature Electronics, realizing the application of photonic chip clocks in information systems for the first time in the world. This technology is based on mass-produced ultra-low-loss silicon nitride photonic chips, and generates high-precision, low-noise clock signals through optical frequency combs, breaking through the performance bottlenecks of traditional electronic chips in terms of clock bandwidth, energy consumption and noise. It provides an important solution for the development of future ultra-high-speed chips.
