Guangming Daily reporter Zhang Yaxiong, Dong Cheng, Zhang Xiaohua

The 2023 Zhongguancun Forum was held in Beijing from May 25 to 30, which features national, cutting-edge and internationalization, and sets up a wealth of forum meetings, exhibitions and other sections. At the scene of the 2023 Zhongguancun Forum Frontier Information Technology Exhibition Area and the 2023 Zhongguancun Forum Exhibition (Science Fair), the reporter saw complex "photonic information" products and innovative products such as chips and unmanned helicopters. What's so subtle about these high-tech products? What is behind its growth? The reporter interviewed relevant experts about this.

Photonics industry, chasing "light"

In the context of Moore's Law reaching its limit, it is increasingly difficult to further effectively improve the information density and rate. As one of the underlying driving forces for human development, information is developing explosively, especially in the fields of artificial intelligence, cloud computing, and intelligent driving.

"With its ultra-high speed, ultra-parallelism, ultra-high bandwidth and ultra-low loss excellent physical characteristics, 'photonic' is considered to be the cornerstone of the new generation of information technology, which can effectively solve the problems of information transmission rate and power consumption." The photonics industry is also considered to be the most strategic, fundamental and leading emerging industry in the 21st century. And now, we are in the paradigm shift phase from integrated circuits to integrated optical paths. Mi Lei, founding partner of China Science and Technology Innovation Star, said.

In the 2023 Zhongguancun Forum Frontier Information Technology Exhibition Area, the reporter saw that Sunward Optoelectronics brought metasurface optical chips. According to Mi Lei, this product can further miniaturize traditional cameras and transform them into "super eyes" on the basis of having both spectrum, polarization, depth and other functions, which is expected to solve the problem of object recognition and detection in harsh environments such as low light and low contrast such as rain, fog, dust and darkness, and accurately obtain information for applications in autonomous driving and security fields. The same technology can also be applied to precision medicine to help with cancer detection.

Mi Lei told reporters that in the field of information transmission, although 5G has been popular, most of the needs of the public can be met, but with the development of communication and AI, the existing transmission rate and security reliability can not meet its needs, so higher speed optical communication chips are particularly critical, but for a long time these technologies have been in the hands of foreign manufacturers. The 25G laser chip exhibited by Yuanjie Technology provides a boost for the development of high-end optical chips and artificial intelligence. At present, the 25G products produced by Yuanjie Technology have been shipped, the 50G products have been verified by customers, and the research and development of 100G products is progressing smoothly.

Mi Lei introduced that in the field of information processing, computers have been pursuing to surpass the human brain. Studies have shown that the brain has 86 billion neurons, can make judgments on certain complex things in a very short time, and the energy consumption is very low, such things can take tens of minutes if calculated by supercomputing. Computers using photonic chips may achieve high-speed, low-power computing like the human brain. For example, PACE, developed by Xizhi Technology based on core technologies such as photonic matrix computing, on-chip optical network and inter-chip optical network, integrates more than 10,000 photonic devices in a single photonic chip, runs a 1GHz system clock, and runs NP complete computing problems hundreds of times faster than current high-end GPUs.

"In the field of information display, the screens we come into contact with daily are mainly OLED, which are often used in display fields such as mobile phones, computers, and televisions. However, OLED screens will burn the screen, flash eyes, etc., and cannot support high resolution, and for users, the 'friendliness' is insufficient. Mi Lei said, and Micro-LED has self-luminous characteristics, which can not only maintain high brightness, high definition, but also have a long service life, "Saflex, which participated in this exhibition, brought original nanoporous quantum dot color conversion technology, solved the long-standing problems of low red light efficiency and RGB integration of microdisplay chips, and provided richer colors, higher efficiency and better performance for the next generation of display applications." ”

"Photonic technology is the root technology and the core technology that promotes scientific and technological progress." Mi Lei said that in the cutting-edge information technology exhibition area, Xifeng Optoelectronics, Orange Microelectronics, Kunyou Optoelectronics, Ruisi Zhixin, Photon Arithmetic, Zhuo Lei, Zhongke Microfine and other enterprises have brought their latest photonic products to the exhibition, "In the future, the cost of optics may account for 70% of the cost of all technology products." ”

Specialized and special new "little giants", on the rise

Small and lightweight water pump products, 5G GaN power devices and 5G millimeter waverate chips, new aircraft engine core components single crystal turbine blades, MK18 unmanned helicopter... In the Shunyi exhibition area of the 2023 Zhongguancun Forum Exhibition (Science Fair), the exhibits reflect the gold content of scientific and technological innovation in Shunyi District, Beijing.

As an important part of Beijing's construction of an international science and technology innovation center, Shunyi District actively participated in the exhibition with the theme of "Beijing Innovation Industry Cluster Demonstration Zone", focusing on displaying the scientific and technological innovation achievements of the three leading industries in Shunyi District on the north side of the exhibition area, and the enterprise development achievements of Beijing Sino-German Industrial Park Park on the south side.

This time, Shunyi District selected a number of scientific and technological achievements of 30 enterprises to participate in the exhibition. Among them, there are 4 in the field of new energy intelligent vehicles, 3 in the field of aerospace, 5 in the field of third-generation semiconductors, 4 in the field of strategic emerging industries, and 14 enterprises in the Sino-German Industrial Park.

According to the relevant person in charge of the Shunyi District Science and Technology Commission, in recent years, Shunyi District has taken the innovation industry cluster demonstration zone as the main position, and has promoted the construction of Beijing International Science and Technology Innovation Center in depth, and the regional scientific and technological innovation, competitiveness and influence have been significantly improved, and the supporting role of scientific and technological innovation for high-quality development has continued to appear. The number of national high-tech enterprises in the region has achieved double-digit growth for many consecutive years, and a number of science and technology-based small and medium-sized enterprises, "specialized, specialized and new" enterprises and "little giant" enterprises have been introduced and cultivated.
