Since its inception, VCSEL has been used as a core device for next-generation optical storage and optical communication applications, and is gradually used in industrial heating, environmental monitoring, medical equipment, and 3D sensing. Recently, I learned that a company that can provide VCSEL epitaxial products for customers from multiple countries-Quan Lei Optoelectronics Co., Ltd. (EPIHOUSE, below Referred to as “Quan Lei Optoelectronics”)
“Quan Lei Optoelectronics” was established on November 17, 2016, focusing on the development, production and sales of compound semiconductor material epitaxial wafers, including a variety of InP and GaAs-based optoelectronic products, for the optical communication and smart sensing industries Provide high-performance laser and detector epitaxial wafer. According to public information, the company has obtained 4 patents for utility models of DFB lasers and 1 patent for utility models of BAR structure in the past year. According to statistics, since its establishment, the company has obtained 9 invention publication patents, 1 invention authorization patent and 8 utility model patents, all of which have passed the national ISO9001 quality certification management system.
In terms of technology, according to the company’s official website information, “Quan Lei Optoelectronics” has a complete MOCVD material epitaxial production line and a matching inspection center, which can produce various types of epitaxial wafer products, including laser epitaxial wafers (FP/DFB/ VCSEL), detector epitaxial wafers (MPD/PIN/APD), electronic device epitaxial wafers (HBT/HEMT), photonic power epitaxial wafers, custom-made epitaxial wafers.

According to the public speech of Quan Lei’s deputy general manager Shan Zhifa, as of December 2018, the world’s first VCSEL application conference, the company has achieved mass production of VCSEL epitaxy, and completed the 940nm VCSEL epitaxial wafer, QWIP and other epitaxial wafer Mass production, and VCSEL epitaxial products have been widely supplied to many customers in mainland China, Taiwan, South Korea, Japan and so on. Shan Zhifa said that the company and the Canadian company have built the most advanced device simulation design center. In the future, Quan Lei Optoelectronics will continue to focus on the field of semiconductor epitaxial wafers. The comprehensive layout covers 3D face recognition, autonomous driving, VR, AR, The industrial ecological chain including 5G, and all-round cooperation with top compound semiconductor research institutions at home and abroad.
According to the company’s official website, the compound semiconductor research institute of Quanquan Optoelectronics is the company’s core research and development institution. The company has a core team of domestic and foreign industry experts, doctors and masters. According to public information, the chairman of Quan Lei Optoelectronics Zhang Yong, a senior engineer, is mainly engaged in research in semiconductor materials, chips and other related fields. He once led the team to undertake three national “863 Program” projects, develop dozens of new products and technologies, and create profits of over 100 million yuan. Zhang Yong has applied for 172 patents, obtained 102 authorized patents, and published 17 academic papers.
According to the disclosed industry and commerce information, “Quan Lei Optoelectronics” has not yet had financing trends, and Zhang Yong is the actual controller of the company.
