Changjiang Daily- Changjiang Network November 11, 2020 November 11-13, 2020, the 17th "China Optics Valley" International Optoelectronics Expo and Forum (hereinafter referred to as: Optical Expo) was held in Han, the same period of the forum closely followed the optical frontier, around the integrated optoelectronics, optical networks, biomedical optoelectronics and other scientific and technological innovation fields, as well as laser advanced manufacturing technology, laser industry, 5G optical communications, new infrastructure, silicon optical chips, optical fiber sensing, silicon light industry and other hot technology directions, held a multi-layer summit forum, special reports Focus on the new trend of the optoelectronic industry.
It is understood that at present, Wuhan is focusing on building an optical core screen end network industry cluster, vigorously developing the optoelectronic information industry, building a photonic science, life science, scientific policy with the world's advanced level, focusing on solving major areas and key core technology problems, promoting technological progress, enterprises into the group, industry into the park, and promote the modernization of the industrial chain.

Liu Wenqing, director of the National Environmental Optical Monitoring Instrument Engineering Technology Research Center and academician of the Chinese Academy of Engineering:
Not only can it be done but also used, it can be considered "Made in China"
Liu Wenqing introduced that although from the perspective of the global innovation development pattern, China is still in a country that is catching up with innovation, but in the innovation ranking, China has been rising, in addition, from the perspective of the development of high-tech industries in The Chinese and American manufacturing industry, for more than 20 years, the global proportion of China's manufacturing industry has risen, and the United States is declining. China's development has profoundly changed the global pattern.
"More than 20 years ago, most of our country's air quality automatic detection systems came from overseas, and none of them were domestically produced. Moreover, there is no listed company. Now that we have more than a dozen listed companies in this field, China has developed a series of atmospheric environment monitoring technologies.
Liu Wenqing introduced that scientists use "light" means to monitor, "a variety of atmospheric components have their spectrum", using spectroscopic methods to measure ozone. At a petrochemical plant in the field, through monitoring, a leak was captured and a safety accident was avoided.
Liu Wenqing introduced that during the epidemic, the air monitoring team went to Wuhan Vulcan Mountain, Leishen Mountain, Jinyintan and other places to explore whether some components in the air in specific places would change during the epidemic. In the end, it was found that the negative pressure system in the square cabin, hospital, etc. played a very large role, and the closed system of the hospital was verified to be very effective, and it was difficult to leak aerosols from the ward into the space.
"Whether we can achieve it or not, we can achieve it, but we can't use it, we can't use it." Liu Wenqing said that the core technology is subject to people, mainly because the core technology is challenged, "the reason why it can't be used is your stability, reliability (can't be reached), and Made in China still has a long way to go." ”

Xu Hongxing, professor of Wuhan University and academician of the Chinese Academy of Sciences:
If basic science is not taken seriously, the industry will not go far
Xu Hongxing said that "light" has pulled a series of high-value industrial chains, such as the 5G industry chain that is forming, which has had a huge impact on unmanned driving, the Internet of Things, semiconductors, cloud computing, the Internet of Things, and the Internet of Everything. For example, for medical devices, semiconductor imaging, in vitro diagnostics and other aspects will use a lot of optical technology.
He believes that "light" is still to build the future industry, "with light for 3D manufacturing, promote some building energy saving, biomedical, precision processing, etc., the future can also use light for mobile phone special-shaped screen manufacturing, everyone's screen can be privately customized, light energy benefits mankind." ”
Xu Hongxing believes that there are two new pain points in the country, one is the aircraft engine, and the other is the chip, both of which are related to optics. For example, the aero engine needs a large thrust-to-weight ratio, the temperature difference requires special materials, and it is necessary to study the interaction of photomatoids and the precision control of light; the other is a chip, the key of which is the lithography machine, and the core of the lithography machine is the light source.
"If we don't pay attention to basic science, then our industry will not go far." Xu Hongxing said that these pain points not only belong to the country, but also relate to the development of each of us, and even the industry itself.

Huawei Technologies Co., Ltd. Fellow Cui Xiuguo:
Scientists and engineers work together to unshackle the stuck neck
Huawei Technologies Co., Ltd. Fellow Cui Xiuguo believes that China has developed very well in the field of optical devices, "After this round of development, our lasers have really been blooming in China, sparking, and have been very mature." Heavy Industries' technological creations are changing our lives. ”
He believes that the entire industrial tree of light has borne fruit, from applications to architecture to chips, forming a towering tree. "The bigger the tree, the deeper the roots, and if we can't root down the tree, the tree will be unstable, and the roots are our materials, our processes, our theories."
He said that around the light industry, we must coordinate the industry, unite a group of scientists and many engineers to the industrial army, and unremittingly persist, and we will certainly be able to unshackle the "stuck neck" shackles in our generation.
