The company has applied for more than 40 domestic and US invention patents and says its core technologies are fully self‑controlled. Ruishi has mass-produced multiple high-performance VCSEL chips, optical integrated light-source products, and optical modules, and has achieved revenues in the tens of millions of RMB. It provides a full-stack technology offering from VCSEL chip design and mass production to optical integrated packaging, sensing algorithms, and application solutions. The company built a 2,000 sqm packaging and testing factory in Guangming, Shenzhen to support stable mass production. Proceeds from the recent financing will be used mainly for VCSEL light-chip technology and related product R&D and market expansion.
