On December 10, 2021, the 2021 China Innovation and entrepreneurship achievements Fair (hereinafter referred to as the innovation and entrepreneurship Fair) with the theme of "enabling double cycles to help new development" opened in the exhibition hall of Guangzhou Pazhou Canton Fair. Shenzhen Zkosemi Semiconductor Technology Co., Ltd. was invited to attend the meeting and appeared in this innovation fair.

The 2021 innovation fair was hosted by the China Association for science and technology, the national development and Reform Commission, the Chinese Academy of Sciences, the Chinese Academy of engineering, the Central Committee of the Jiusan Society, the Guangdong Provincial People's government and the Guangzhou Municipal People's government, and undertaken by the Guangzhou Municipal People's government and international data group. It was held from December 10 to 12, 2021 for three days.

This time, Shenzhen Zkosemi Semiconductor with the domestic leading single tube 50Gbps VCSEL optical chip products appeared at the 2021 innovation fair.

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 industrialization of optical chip / optical module in China is still in the early stage. There are not many domestic enterprises capable of producing photoelectric chips, 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 chips, but the production capacity is limited, accounting for less than 1% of the market. According to the development roadmap of China's optical device industry (2018-2022), optical chips with a speed of 25gb / s 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 50GB optical modules, while the Japanese manufacturers also have the ability to support pam4 (400g optical modules).

At this exhibition, Shenzhen Zkosemi Semiconductor talked with experts, scholars and entrepreneurs in the industry, and received the attention of well-known media CCTV.
