"Scientific and technological innovation relies on investment and talent. I am very happy to see that there are many elite talents gathered here, and everyone is young and full of energy. On June 2022, 6, General Secretary Xi Jinping emphasized during his inspection tour in Wuhan, Hubei Province, during cordial exchanges with enterprise employees.

Over the past year, young people in Wuhan who have been fighting on the front line of scientific research and technology research and development have kept in mind the important instructions of the general secretary and worked hard and bravely. Young forces are chasing the light and shining on the journey of scientific research!

"It is urgent to break through the key core technologies of the 'stuck neck'", "work hard, catch up, and accelerate the realization of scientific and technological self-reliance and self-improvement"... A year ago, in front of the workshop building of Wuhan Huagong Laser Engineering Co., Ltd., General Secretary Xi Jinping's speech was loud, and Feng Xinkang, process director of Huagong Laser Semiconductor Panel Division, still remembers it vividly.

"This is it! On June 6 last year, we listened to the general secretary's teachings downstairs. Feng Xinkang pointed out the window, "The general secretary has great expectations for our generation of young scientific research forces, which makes us feel that we have a stronger sense of mission in our work and must catch up!" ”

The young people on the 13th floor of Wuhan Ruike Fiber Laser Technology Co., Ltd. are also "very busy". A colleague in the optical device department turned on his mobile phone hands-free, quickly moved from the other end of the "Chase Shop" to the optical engineer Zhang Haiyang, skillfully pulled the chair next to him and sat down, and a remote meeting began.

"The world's martial arts, only fast can not be broken, and there is no delay for a moment!" Most of the colleagues are post-90s, working in such an environment, they can efficiently 'chat' and solve problems at any time. Zhang Haiyang said bluntly.

Zhang Haiyang said: "The partners of our project team raced against time to completely replace imports with the nationally produced 3D printing lasers developed and successfully applied to the 3D printing industry!" ”

In this year, a number of major scientific and technological innovation achievements such as the first 1.6Tb/s silicon photointerconnection chip in China, the first 2K high-frequency PWM flexible screen in China, and the national EDA software were born in Optics Valley.

Six years ago, Feng Xinkang left a foreign company in Shanghai to manufacture laser processing equipment and joined Huagong Laser.

"The research and development and assembly of key equipment are all abroad, and the core technology is not allowed to be touched." Speaking of the reasons for changing jobs, Feng Xinkang made an analogy, "In foreign companies, I am more like a 'screw' that will be replaced at any time." Only when we return to our country's enterprises can they become irreplaceable 'core components'. ”

As Feng Xinkang said, Huagong Laser also provides a bigger stage for this young man.

"Looking back over the years, I have been deeply involved in the research and development of core technologies." Now 34 years old, Feng Xinkang has grown into a business backbone, "At Huagong Laser, I have witnessed the process of accelerating the domestic substitution of many of our laser processing equipment; Domestic hot sales, overseas orders are also a steady stream. ”

Speaking of this, Feng Xinkang sighed, "While participating in the national strategy, I also have a sense of accomplishment. For national scientific research, with honor! ”

Now, Feng Xinkang has a new goal. "The laser equipment we are developing is aimed at the most advanced and difficult area of industry - semiconductors. I believe that as long as the goal is firm and the two-inch wide thing is made two feet deep, it will definitely be achieved. In Feng Xinkang's view, the beautiful picture of self-reliance and self-improvement of science and technology is in front of him.

"100% localization is a new beginning for me, and I must take a longer-term view." Zhang Haiyang said, "Not only let our country's enterprises use easy-to-use and affordable laser products, but also give full play to the role of the enterprise industrial chain master and the source of the laser industry, and take up the mission of the 'national team' in the field of laser light sources." ”

Optics Valley gathers "light" into a valley, and the optoelectronic information industry is unique.

Today, in Optics Valley, local leading enterprises such as China Xinke, Huagong Science and Technology, and Changfei have become "chain masters", and a number of science and technology enterprises have accelerated their growth, with a total of 5200,<> high-tech enterprises.

Xiao Xi, Deputy Director of the National Key Laboratory of Optical Fiber Communication Technology and Network of China Xinke Group, shared the latest progress happily: "In May this year, we realized the single-mode 5-core optical fiber transmission system experiment with a total transmission capacity of 4.1Pb/s and a net transmission capacity of 3.61P/s, which broke the world record for single-mode multi-core optical fiber transmission capacity and is also the highest level of experimental capacity of domestic optical fiber transmission system. ”

In the past 4 years, Xiao Xi's laboratory has increased the experimental capacity of the optical fiber transmission system by 4 times, and now a single optical fiber can transmit 60000,<> high-definition movies per second, marking a big step in the field of optical communication in China.

In the past 10 years, China Xinke Group has also changed from a "layman" to a "bull ear holder" in the frontier field of silicon photonics, cultivating a number of leading silicon photonics chip technologies. Xiao Xi has also gradually grown from a scientific researcher to a "pilot" of technological innovation and a "ferryman" of industry-university-research transformation.

"What I want to do now is not only to lead the team to make more technological breakthroughs, but also to use the National Information Optoelectronics Innovation Center as a platform to actively integrate the optoelectronics industry chain and innovation chain, drive more innovative achievements to industrial applications, and contribute to China's optoelectronic information industry taking the lead in achieving breakthroughs."

Xiao Xi said that in accordance with the general secretary's guidance, he will continue to shoulder the mission of "chasing the light and building the core", focus on the "stuck neck" field, focus on building a big country and heavy weapons, and occupy some commanding heights faster.
