Hosted by the Haining Municipal People's Government, the "core" dynasty city of Haining City Economic Development Zone, the future Haining (China) Pan-Semiconductor Industrial Park, Xinyihua, Phase I Project, China, China On the form of live broadcast, five major projects completed by this completion involve intelligent equipment, key components, new energy, etc. have reached 503 billion yuan, and the annual output value is expected to be 10.12 billion yuan.
As a co-organizer, the Co-organizer (Haining) Science and Technology Co., Ltd., one of the Co-gardeners, is a company that is introduced by the general semicractive industry in Haining Economic Development Zone in Zhejiang Province. The company was established on the basis of the integration of the original Zhongke Tianqi Technology (Beijing) Co., Ltd. and Xiamen City and Yuhua Optoelectronics Technology Co., Ltd., in Haining, Beijing, Xiamen, Shenzhen and other places have R & D, production and sales institutions. Guojiao light relocation provides customers with a variety of core silicon-based photon chip technology and solutions based on various application scenarios from consumer electron to automatic driving.
The company team was born in the Chinese Academy of Sciences, with more than 20 years of research in the silicon field, accumulated a large number of technical experience and top talents, one of the first teams engaged in related fields in China. Since 2017, the company has launched production and research cooperation in the form of a joint laboratory and other forms, and in February 2018, the first generation of optical phased array technology solid state laser radar chip A2. The company's R & D team has continuously optimized improvements in this basis. In August 2019, the new generation of optical phase-controlled array technology solid-state laser radar chips, and organized third-party experts to review the results of this flow, unanimously recognized This stream reaches domestic leading, internationally advanced levels.
In order to adapt to the demand for the application and mass production of the car phase control, the national optical core has been developed through the development of two years, and has built a new silicon-based material system and cooperates with the world's leading technology enterprises. Previously carrying light power in the laser radar in the vehicle-in-vehicle-controlled laser radar, a number of international technical problems such as the interference of the side flap, completed the laser radar scanning chip (chip and packaged samples after the package) of large-scale mass production. Figure 2), the application of the truly car-mine-controlled laser radar clears the key technique barrier.

On the technical route, the national optical core is based on the new silicon-based material system waveguide, and has developed a laser radar scanning chip that can be customized from 780 nm to 1650 nm. This chip uses low-transmission loss, weak nonlinear technology advantages, with a comprehensive and significant advanced feature compared to traditional photon material systems, ensuring that the waveguides of several hundred nanometer width can be loaded larger than the tile continuous light or The peak power kWh pulse laser energy provides feasibility for car laser radar applications for 100 meters or even kilometers. At the same time, due to the adoption of the new material system, the coupling loss of 1 dB and the transmission loss of about 0.1 dB / cm are guaranteed. In addition, using original hardware design, software development of intelligent adaptation algorithms, realizes a number of side lobular suppression ratios compared to traditional phased array techniques. After encapsulation, the chip can achieve a wide scan angle, high-standard, large contrast laser beam scan, and achieve ideal combination with optical integrated coherence detection techniques. The chip manufacturing process is compatible with CMOS technology, with large-scale, low-cost industrial feasibility, and large-scale production costs can be less than 30 US dollars.

In addition to the laser radar scanning chip, the national optical core is also significantly improved in terms of frequency modulation continuous wave coherence detection, beam control, etc., and plans to develop low-cost full solid-state laser radar modules based on phased array scan chips within 2020.
