Recently, the key technology and industrialization of optical network splitter chip and arrayed waveguide grating chip of the Institute of Semiconductors of the Chinese Academy of Sciences won the second prize for the national technology invention in 2017.
The report of the Nineteenth Congress proposed that 'innovation is the primary driving force for development' and 'supporting the optimization and upgrading of traditional industries'. On March 28th, the first person to be accomplished by the project, An Junming, a researcher at the Institute of Semiconductors of the Chinese Academy of Sciences, was accepting an exclusive Xinhua News reporter’s report. During the interview, he stated that China's optical communication industry is in a stage of development. It is necessary to promote application innovation through originality and basic theoretical innovation, and strive to reach the world's leading level as soon as possible.
Transforming from alternative trackers to innovation leaders
The report of the Nineteenth Congress proposed that 'innovation is the primary driving force for development' and 'accelerating the construction of an innovative country'. In response, An Junming stated that the party’s report on the Nineteenth Congress proposed that 'innovation is the primary driving force for development'. Is a very wise, very visionary strategic requirement.
According to him, China's optical communications high-speed core chips are in the development stage, and there is still a big gap with the United States, Japan and other countries. The current global optical communications industry, high-end chips, device products are almost all dominated by the US and Japan manufacturers, and domestic in this The aspect is basically blank or is in the research and development stage.
'Each of our scientific and technical personnel has a sense of mission, responsibility and sense of urgency. This needs to start from the source, pay attention to originality and basic theoretical innovation, use basic theory to promote applied innovation, and pay attention to the formulation and participation of international standards. Only in this way Only from an alternative tracker to innovation leader. ' An Junming said.
Faced with the current situation of heavy tasks and heavy responsibilities, An Junming believes that the scientific and technological communities and the business community should work together to work together for the rapid development of China’s optical communications high-speed core chips. Countries should also increase key technologies common to optoelectronic chips. R&D financial support, rapidly increasing the localization rate of core devices, making innovation the first driving force for national economic development.
With high-definition video, web conferencing, mobile communications, and other requirements for network download speeds and network capacity are increasing, high-speed, high-capacity optical networks have become an inevitable trend of development. 'Through the optical splitter chip and arrayed waveguide grating ( AWG) The technological breakthrough of the two chips of the chip, we successfully implemented industrial transformation and replaced imported chips. The chip has been widely used in the construction of China's optical network, which has enhanced the core competitiveness of our broadband network construction. 'An Junming said.
In recent years, with the country’s encouragement and support for independent innovation of enterprises, Chinese companies are paying more and more attention to R&D investment and patent protection of core technologies. According to An Junming, the optical splitter chip and AWG chip of this project contain core designs. There are a total of 17 core patents for technology and packaging, and more than 30 peripheral patents, forming independent intellectual sovereignty. Since Chinese companies mainly use out-of-the-chip chips and packaging, China’s early patents were mainly concentrated in large research institutes and universities’ research institutions. In recent years, with the national encouragement and support for independent innovation of enterprises, Chinese enterprises have increasingly attached importance to R&D investment and patent protection of core technologies, and enterprises have formed a series of patents from chip design, process to packaging, and presented A year-on-year growth trend. ' An Junming said.
Open up the entire industry chain of optical communication to promote the transformation and upgrading of the manufacturing industry
The report of the Nineteenth Congress also proposed: 'Accelerate the construction of manufacturing powers, accelerate the development of advanced manufacturing', 'Support the optimization and upgrading of traditional industries', 'Promote China's industries to enter the high-end of the global value chain, and nurture several world-class advanced manufacturing clusters'. In the current third wave of global informatization, the optical communication industry will play a key role in boosting the transformation and upgrading of China's manufacturing industry and upgrading digitalization to intelligence.
An Junming believes that China has a very good foundation in the field of optical communication industry and transmission; in optical communication systems, device packaging and Internet + applications, the proportion in the global industrial chain is increasing, and it has taken the lead in the world; Delayed industrialization in high-speed optoelectronic chips.
To fully realize industrialization, he said, 'The high-speed optoelectronic chip industry needs to open up the entire industry chain of optical communications to realize chips, devices, systems and Internet+ applications, which will be the ultimate goal of China's optical communications industry.'
In the third wave of global informatization, science and technology such as Internet of things, big data, cloud computing, Internet+ and intelligent manufacturing will be fully rolled out. These applications cannot be separated from ultra-high speed, large capacity, low latency optical networks. As a backing for hardware, An Junming said, 'A fast-response, reliable guaranteed optical network will play a strong supporting role in information applications, and will transform China's manufacturing industry into a digital one and intelligently enhance it. enhancement. '
Regarding the outstanding achievements of the project, An Junming believes that this is the result of the team's joint efforts. It is also the result of the country's strong encouragement to support the independent and controllable core technologies. Turning to the future development direction, he said, 'In the optical splitter and AWG While expanding and expanding, we will further explore new application scenarios, and explore the application research of quantum codec chip and laser radar based on optical waveguides to promote optical waveguide materials, advancement of high-end core chip technology, and serve the development of the national economy.
