On January 6, sponsored by Guoqiang Research Institute of Tsinghua University, Artificial Intelligence Research Institute of Tsinghua University, Guangdong Guoqiang public welfare foundation, Guangdong bozhilin robot Co., Ltd The final and award ceremony of the second "Tsinghua University Guoqiang Research Institute Cup" global AI and robot innovation and entrepreneurship competition hosted by Lihe Kechuang Group Co., Ltd. was held in bozhilin robot headquarters building in Shunde, Foshan. After fierce competition throughout the day, the technological innovation race track, application scenario race track and 38 special awards were announced one by one.

The second "Tsinghua University Guoqiang Research Institute Cup" global AI and robot innovation and entrepreneurship competition is a global, high standard, high-level and professional large-scale event. Following the innovative mode of "demand traction, event discovery and industrial cultivation", the competition found and cultivated a number of innovative achievements in artificial intelligence and robot science and technology around the world, focused on the four regions around the Bohai Sea, the Yangtze River Delta, Guangdong, Hong Kong, Macao and the central and Western regions, and added international special sessions and special sessions for colleges and universities. Affected by the epidemic situation, the competition was launched online in November. It is divided into five stages: project collection, audition, promotion, final and award. There is a special two track competition system. A total of 450 artificial intelligence and robot projects from home and abroad signed up for the competition. Among them, the technological innovation competition involves innovative technologies such as unmanned system, intelligent perception and man-machine mixing. The application scenario competition aims at solving practical problems in the application scenarios of key collection fields, including construction, community service, commerce, industry, agriculture, medical treatment, education For family and special assignments, 27 projects were selected to participate in the final of the technological innovation competition in the form of roadshow.

Shenzhen Zkosemi Semiconductor won the third place this time, which comes from the hard core technology of the enterprise. Founded in 2020, Shenzhen Zkosemi Semiconductor Technology Co.,Ltd. is an emerging high-tech enterprise focusing on the R & D and production of high-speed optical chips VCSEL / DFB / EML, 3D sensing chips and related modules, as well as wafer manufacturing such as epitaxial wafers. The founder of the company is Dr. Zheng Junxiong, who once served as a senior expert in R & D and operation of Huawei Technology, one of the world's top 500 companies; The founder has led a group of leading optical chip companies from the US Silicon Valley's leading optical chip companies and Taiwan, China, focusing on the top experts in high-end optical chip design and wafer fabrication.

"Many of our high-end optical chips have been successfully streamed and have been certified by authorities and tested by customers. Among them, the industrialization of high-speed high-end optical chips based on single channel VCSEL 50Gbps has filled the domestic gap; our optical chips have industry-leading margin and tdecq indicators at room temperature and high temperature, showing high reliability and wide driving range These indicators have reached the world-class level. In addition, we have multi junction technology, flip chip technology and multi partition addressable technology. Among them, the photoelectric conversion efficiency of multi junction has exceeded 55%, and the 3dB bandwidth has exceeded 18GHz. These indicators further verify the core competitiveness of our optical chip. " Dr. Zheng Junxiong introduced.

VCSEL, full name vertical cavitysurface emittinglaser, is a vertical cavity surface emitting laser. It was first used in the field of optical communication, such as optical modules, and then began to be used in 3D sensing in the field of consumer electronics, such as face recognition. In 2017, apple used it in the iPhone face recognition module, and VCSEL also began to receive large-scale attention in the field of consumer electronics. At present, the global laser market can reach US $8 billion, of which VCSEL can reach US $4 billion. The photonic chip industry can leverage the $2.6 trillion market in the future.

At present, the industrialization of optical chips / optical modules in China is still at an early stage. There are not many enterprises capable of producing optical chips in China, about 30. Most of them can only produce low-end chips in large quantities, and only a few manufacturers can produce medium and high-end optical chips, but the production capacity is limited and the market accounts for less than 1%. Highly dependent on imports, including 400g and 800g optical modules are core technologies based on high-end optical chips.

According to the development roadmap of China's optical device industry (2018-2022), optical chips with a speed of 25gbps and above are highly dependent on imports, and the localization rate is only 3%. The first-line manufacturers in Europe, America and Japan have quite high-tech optical chip manufacturing capacity. The first-line manufacturers in Europe and America have the manufacturing capacity of 50Gbps optical chips, and the Japanese manufacturers also have the ability to support pam4 (400g optical module). The industrialization and mass production of single tube 50Gbps high-end optical chips belong to China's domestic blank at present.
