Recently, the "Key Technology and Industrialization of Optical Splitter Chips and Arrayed Waveguide Grating Chips for Optical Networks" of the Institute of Semiconductors of the Chinese Academy of Sciences won the second prize of the 2017 National Technology Invention.
The report of the 19th National Congress of the Communist Party of China stated that "innovation is the first driving force for development" and "supporting the optimization and upgrading of traditional industries." On March 28, An Junming, a researcher at the Institute of Semiconductors of the Chinese Academy of Sciences, said in an exclusive interview with Xinhuanet reporter that China's optical communication industry is in the development stage, and it is necessary to promote application innovation through originality and basic theoretical innovation. Strive to reach the world's leading level as soon as possible.
The report of the 19th National Congress stated that "innovation is the first driving force for development" and "accelerating the construction of an innovative country." In this regard, An Junming said that the party’s report on the 19th National Congress stated that “innovation is the first driving force for development†and it is a very wise and very far-sighted strategic requirement.
According to him, China's optical communication high-speed core chip is in the development stage, and there is still a big gap with the United States, Japan and other countries. At present, the high-end chips and device products of the global optical communication industry are almost entirely dominated by US and Japanese manufacturers, and the domestic market is basically blank or in the research and development stage.
“Everyone of us has a sense of mission, responsibility and urgency. This requires starting from the source, focusing on originality and basic theoretical innovation, promoting applied innovation with basic theories, and focusing on the development and participation of international standards. In order to move from an alternative tracker to an innovation leader," An Junming said.
Facing the current situation of heavy tasks and heavy responsibilities, An Junming believes that the scientific and technological circles and the business community should work together to jointly work together for the rapid development of China's optical communication high-speed core chips. The state should also increase R&D funding support for key technologies common to optoelectronic chips, rapidly increase the localization rate of core devices, and make innovation the first driving force for national economic development.
With high-definition video, network conferencing, mobile communications and other requirements for network download speed and network capacity, high-speed, large-capacity optical networks have become an inevitable trend of development. "Through the technological breakthrough of the optical splitter chip and the arrayed waveguide grating (AWG) chip, we successfully realized the industrial transformation and replaced the imported chips. The chip has been widely used in the construction of China's optical network, which has enhanced our broadband. The core competitiveness of network construction." An Junming said.
In recent years, with the encouragement and support of the state for independent innovation, Chinese companies have paid more and more attention to R&D investment and patent protection of core technologies. According to An Junming, the project's optical splitter chip and AWG chip contain 17 core design, process and packaging core patents, and more than 30 peripheral patents, forming autonomous knowledge sovereignty. Since Chinese enterprises mainly focus on chip purchase and packaging, China's early patents are mainly concentrated in major research institutes and university research institutions. "In recent years, with the encouragement and support of the state for independent innovation of enterprises, Chinese enterprises have paid more and more attention to the R&D investment and patent protection of core technologies. The company has formed a series of patents from chip design, process to packaging, and presented Year by year growth trend." An Junming said.
Promote the transformation and upgrading of manufacturing industry through the whole industry chain of optical communicationThe report of the 19th National Congress also proposed "accelerating the construction of a strong manufacturing country, accelerating the development of advanced manufacturing industries," "supporting the optimization and upgrading of traditional industries," and "promoting China's industry to move toward the high-end of the global value chain and cultivating several world-class advanced manufacturing clusters." In the current wave of global informationization, the optical communication industry will play a key role in boosting the transformation and upgrading of China's manufacturing industry and upgrading from 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 growing, and it is in the forefront of the world; Industrialization has not been realized in terms of high-speed optoelectronic chips.
To fully realize industrialization, he said, "The high-speed optoelectronic chip industry needs to open up the entire optical 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 informationization, science and technology such as the Internet of Things, big data, cloud computing, Internet + and intelligent manufacturing will be fully rolled out, and these applications are inseparable from ultra-high-speed, ultra-large-capacity, low-latency optical networks. Backed by the hardware foundation. An Junming said, "A fast-response, reliable and reliable optical network will play a strong supporting role in information technology applications, and will play a positive role in promoting the transformation and upgrading of China's manufacturing industry, digitalization and intelligent improvement."
For the outstanding achievements of the project, An Junming believes that this is the result of the joint efforts of the team and the result of the state's strong encouragement to support the core technology to control itself. Speaking of the future development direction, he said, "When the optical splitter and AWG become bigger and stronger, further develop new application scenarios, and at the same time explore the application research of quantum codec chips and laser radar based on optical waveguides. To promote the advancement of optical waveguide materials and high-end core chips, and to serve the development of the national economy."
