The 2023 Zhongguancun Forum was held in Beijing from May 25th to 30th. The forum is characterized by national level, cutting-edge, and internationalization, with rich forum meetings, exhibition displays, and other sections. At the 2023 Zhongguancun Forum Frontier Information Technology Exhibition Area and the 2023 Zhongguancun Forum Exhibition (Science and Technology Expo), reporters saw complex "photon information" products as well as innovative products such as chips and unmanned helicopters. What are the subtleties of these high-tech products? What is the driving force behind its growth? The reporter interviewed relevant experts on this matter. In the context of Moore's Law approaching its limit, the photon industry is chasing after "light", and it is becoming increasingly difficult to further effectively improve information density and speed. As one of the underlying driving forces for human development, information is rapidly advancing, especially in fields such as artificial intelligence, cloud computing, and intelligent driving. 'Photonics' is considered the cornerstone of the new generation of information technology with its excellent physical characteristics of ultra-high speed, strong parallelism, ultra-high bandwidth, and ultra-low loss, which can effectively solve the problems of information transmission rate and power consumption. The photon industry is also considered the most strategic, fundamental, and pioneering emerging industry in the 21st century. Now, we are in the stage of paradigm shift from integrated circuits to integrated optical circuits Mi Lei, founding partner of Zhongke Chuangshing, said. At the 2023 Zhongguancun Forum Frontier Information Technology Exhibition Area, reporters saw that Shanhe Optoelectronics has brought ultra surface light chips. According to Mi Lei, this product can further miniaturize traditional cameras and transform them into "super eyes" on the basis of combining spectral, polarization, depth and other functions. It is expected to solve the problem of object recognition and detection in harsh environments such as low light and low contrast in rainy, foggy, dust, and darkness, accurately obtaining information, and applying it to fields such as autonomous driving and security. The same technology can also be applied to precision medicine to assist in cancer screening. Mi Lei told reporters that in the field of information transmission, although 5G has become very popular and can meet most of the public's needs, with the development of communication and AI, the existing transmission rate and security reliability cannot meet their needs. Therefore, higher speed optical communication chips are particularly crucial, but these technologies have long been in the hands of foreign manufacturers. The 25G laser chip exhibited by Yuanjie Technology this time has provided assistance 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 are under customer verification, and the development of the 100G products is progressing smoothly. Mi Lei introduced that in the field of information processing, computers have always been striving to surpass the human brain. Research has shown that the brain has 86 billion neurons, which can make judgments on complex things in a very short period of time, and the energy consumption is very low. If supercomputing is used to calculate such things, it may take several decades. Computers using photonic chips may achieve high-speed and low-power operations similar to human brains. For example, Xizhi Technology's PACE, developed based on core technologies such as photon matrix computing, on chip optical networks, and inter chip optical networks, integrates over 10000 photon devices in a single photon chip and operates
