2021 Excellent Domestic Substitution Performance Enterprise

RAYSEES is a high-tech company originating from Silicon Valley, founded by a team of American returnees with PhDs. RAYSEES has the world's leading core technologies and mass production capabilities such as VCSEL optical chip design, optical integrated packaging, algorithm development, optoelectronic system integration optimization, etc., and has opened up the entire industry chain of "chip design-packaging test-optical integration", and launched multiple series of high-performance VCSEL chips and optical integrated light source products, providing industry-leading optical chips and optical sensing solutions for customers in industries such as artificial intelligence, face recognition, robot vision, lidar, AIoT smart hardware, etc.

Ruishi Technology has been deeply engaged in the field of compound semiconductor optical chips. With its strong semiconductor optical chip design capabilities, it has broken through the performance bottleneck of VCSEL optical chips. In the process of cooperating with top domestic and foreign foundries, it has established stable cooperative relationships relying on professional and efficient foundry management. The mass production yield and stability of its optical chip products have reached the world's leading level.

Multi-junction VCSEL ToF light source

①Product performance:

Ruishi's multi-junction ToF VCSEL chip can achieve high power in a tiny light-emitting area that requires multiple single-junction VCSEL chips. Under low duty cycle (a few thousandths) nanosecond pulse width driving conditions, its optical power is nearly 3-5 times higher than that of the iToF array VCSEL chip under the same driving conditions. At the same time, the photoelectric conversion efficiency is higher than the average 45% conversion efficiency of ordinary single-junction VCSEL chips.

②Price competitiveness:

Ruishi's multi-junction ToF VCSEL chip mass production is completely 100% domestically produced, which has a great price advantage over similar imported chips. The epitaxial growth and chip manufacturing processes of multi-junction chips are modified based on the existing single-junction VCSEL chip process, and its mass production has been verified.

③Technological innovation:

Ruishi's multi-junction ToF VCSEL chip epitaxial design breaks through the traditional VCSEL chip idea of ​​increasing the light-emitting area to increase the optical power. Without increasing the chip size and area, by increasing the number of active areas (number of junctions) in the VCSEL chip epitaxial structure, the overall performance of the VCSEL chip is improved to several times that of a single-junction VCSEL chip.

④Customer Service:

Ruishi VCSEL chips have passed multiple reliability certifications from authoritative third parties and customers with zero failures. Chips can be quickly customized according to customer needs.

Reasons to vote for Ruishi Technology:

Raysees is committed to becoming a leader in VCSEL optical chips and optical sensing solutions. In the three years since its establishment, the company has applied for 46 domestic and foreign invention patents and has completely independent intellectual property rights for its core technologies. Its products have been tested and verified by Chinese machine solution companies and mobile phone manufacturers. It is currently the only optical chip company in China that has deeply cultivated the three fields of VCEL optical chips, optical integration and application modules. Raysees has independent VCSEL optical chip design, optical integration, and application system integration capabilities, and has achieved a 100% domestic production supply chain. Its mass-produced products include VCSEL optical chips and optical integrated light sources, which can be used for all current consumer-grade optical sensing solutions such as structured light, ToF, active binoculars, and lidar. Raysees has currently completed three rounds of financing, with a total amount of over 200 million yuan.
