Recently, Chinese scientists have made a huge technological breakthrough in the field of photonic chips, successfully proposing a new method to slow down the speed of light on photonic chips. This has aroused widespread attention in the technology community, and photonic chip technology has once again become a hot topic.
Chang Lin, a researcher at Peking University's Advanced Integrated Photonic Chip Laboratory, said that photonic chips use light as a signal carrier, which has higher computing power and lower energy consumption than traditional electronic chips. He believes that photonic chips are expected to be widely used in smartphones and computers in the next 5-10 years.
Li Guangyuan's team at the Shenzhen Institute of Advanced Technology of the Chinese Academy of Sciences has proposed a new method to slow down the speed of light on photonic chips. This innovation is expected to greatly improve the performance of slow-light photonic chip devices, and gain a wide range of applications in the fields of optical sensing, optical communication, optical computing, and optical buffering, providing new ideas for the research of slow-light technology. The findings were recently published in Nano Letters.
The rise of photonic chip technology marks a major change in the field of information technology. Compared with traditional electronic chips, photonic chips have higher speed, lower energy consumption, and stronger computing power, providing strong support for industries such as artificial intelligence, Internet of Things, and cloud computing. The advantage of photonic chips is that light travels very fast and consumes almost no energy during information transmission, which provides a more efficient solution for information processing and transmission.
With the continuous progress of photonic chip technology, its application prospects in various fields have become more and more broad. First of all, in the field of lidar, especially with the popularization of autonomous driving technology, the need for lidar with low cost and performance that meets the requirements of vehicles will become more urgent. Secondly, at the level of optical computing, scientists expect to change the interconnection between the traditional GPU and CPU to the interconnection with light through photonic chip technology, so as to reduce power consumption and improve computing power.
In research at the Shenzhen Institute of Advanced Technology of the Chinese Academy of Sciences, Li Guangyuan's team succeeded with a new method of slowing down the speed of light on photonic chips. By using the interference coupling of two surface lattice resonance modes, they achieved an electromagnetic-induced transparency phenomenon with a strong slow-light effect at room temperature. In the process, the speed of light is successfully slowed down by more than 10,000 times, about 30 kilometers per second. At the same time, the experimental quality factor was as high as 2750, more than five times that of the current record, and the loss was less than one-fifth of the current record. This technological breakthrough brings new possibilities for the application of photonic chips, breaking through the long-standing loss problem in slow light technology.
Scientists are confident in the potential of photonic chip technology. Chang Lin said that photonic chips and traditional electronic chips have completely different logic. In the case of electronic chips, the manufacturing process (the smallest size that can be achieved in the production of the chip) is very important. However, in the case of photonic chips, a photon travels once at the speed of light across the chip to complete a computation. This unique logic architecture is expected to be a game-changer for the entire chip industry.
However, there are still a number of challenges to industrialize photonic chip technology and put it into practical application. Industrialization requires a large amount of financial support, including scientific research funds and industrial investment. The successful industrialization of photonic chip technology also requires the establishment of close connection with the industry and investment community to better meet market demand.
