beijing universityelectronicthe college and the chinese academy of sciences aerospace information research institute make breakthroughs in cooperation: photonic chip clock technology opens a new era of ultra-high-speed information

IT home news, with the rapid development of global information technology, wewelcomea disruptive technological breakthrough.
recently, the researcher team of chang lin of the school of electronics of peking university and the researcher li wangzhe of the institute of aerospace information of the chinese academy of sciences jointly published major research results.
the study announced to the world at some point in february this year: they are in internationally renowned journals NatureElectronics the magazine published online Microcomb-synchronizedoptoelectronics research articles.
the focus of the article is that they have realized the application of photonic chip clocks in information systems for the first time in the world, and have given important solutions to the future development of ultra-high-speed chips.
the technical achievements this time are of great significance in both theoretical and experimental fields, opening a new chapter in global science and technology.

traditional electronic technology is subject to the problem of clock signal generation mechanism.
due to the existing physical theories and technical processes, traditional electronic chips often face problems such as narrow bandwidth, easy signal distortion, and high power consumption when generating high-frequency signals.
this not only limits the performance improvement of electronic devices, but also increasesenergyconsumptionand cost burden.
in optoelectronic systems, the frequency mismatch between optical synthetic signals and electronic clocks has also been plagued by many years.researchers，making synchronization difficult.
therefore, how to break through these technical bottlenecks and achieve synchronous and efficient operation of optoelectronic systems has always been an urgent problem that scientific researchers need to solve.

against this background, the researcher team of chang lin from the school of electronics of peking university and the researcher li wangzhe from the institute of aerospace information of the chinese academy of sciences jointly conducted research.
they studied the working principle of photonic chips in depth, and used existing technical theories and innovative ideas to develop an oscillator based on on-chip microcombs.
this oscillator combines integrated ultra-high Q the microcomb and self-injection locking technology of value resonators have successfully achieved from megahertz to 105 GHz microwave signal synthesis.
it not only provides a shared time-frequency reference for the system, but also makes synchronization of optical and electronic signals possible.
this allows the optical system and electronic system to be better integrated, further improving the efficiency and accuracy of information processing.
this innovative design undoubtedly provides an important solution for the future development of ultra-high-speed chips.

it is more worth mentioning that the research team further demonstrated the multi-band synesthesia integrated system based on this chip.
5 G、6G、 various functions of different electromagnetic wave bands such as millimeter wave radar can flexibly switch between sensing and communication modes.
this innovative design not only simplifies the hardware structure, reduces the complexity and cost of the system, but also achieves centimeter-level perceptual accuracy and modulation format up to 256- QAM 6 G communication.
the practicality of this technology will greatly promote the development of communication technology and improve communication efficiency and reliability.

it is understood that this technology has broad application prospects.
in a processor chip, this solution can increase the clock frequency to 100 G the above provides computing power far exceeding the current chip.
this will greatly improve the performance of computers and promote the rapid development of artificial intelligence, cloud computing and other fields.
in mobile phone base stations, it can reduce the energy consumption and cost of the device and improve the performance and service life of the device.
in the field of autonomous driving, the integrated design of millimeter-wave radar will help improve perception accuracy and response speed, and improve the safety and reliability of autonomous driving.
the widespread application of this technology will greatly promote scientific and technological progress and social development.

the industry has given high praise to this technological breakthrough.
it not only demonstrates my country's strong scientific research strength in the field of information technology, but also provides future developmentstrongoftechnical support。
we believe that in the near future, equipment based on photonic chip clock technology will be widely used in various fields to promote social progress and development.
the successful practice of this technology will also provide scientific researchers with more innovative ideas and research directions, and promote the development and innovation of science and technology.
