On January 21, 2026 ，Raysea made a prominent appearance at SPIE Photonics West 2026 in San Francisco, USA. Dr. Lai, a representative of the company’s R&D team, presented a technical paper at the VCSEL Annual Conference session, elaborating on the latest advancements of Raysea’s fully self-developed multi-junction VCSEL technologies and products for robotics and automotive applications. The presentation garnered enthusiastic responses and strong attention from industry peers.
Addressing the stringent requirements for detection range, precision, and reliability in lidar systems for autonomous driving and embodied intelligence, Raysea’s proprietary Single Oxidation Multiple Junction (SOMJ) VCSEL technology platform delivers five core advantages:Higher optical power and power density；High-duty-cycle operation capability；Superior electro-optical conversion efficiency；Narrower beam divergence；AEC-Qualified automotive-grade reliability.
Based on this technology platform, the company has built a comprehensive product portfolio covering discrete, linear, and area array (including 1D/2D addressable) VCSEL arrays, widely deployed in automotive, consumer & service robots, data communications, industrial systems, and drones.
The interactive Q&A session emerged as a highlight of the presentation. Dr. Lai provided precise and in-depth responses to questions from the audience, detailing Raysea’s technical pathway to achieve the industry’s first 14-junction linear VCSEL array. He also explained how the SOMJ platform enables a power density of up to 10,000 W/mm², maintains a small divergence angle of approximately 10° (with a single-aperture slope efficiency of >7 W/A and slope efficiency loss <10%), and supports mass production for automotive-grade laser sources.The team’s key conclusion “All junction counts are realized with a single oxidation layer structure” ,received high recognition from industry experts, including the session chair.
The session maintained a vibrant atmosphere, with the audience frequently nodding in approval and engaging in on-site discussions. The professional and practical technical sharing earned broad acclaim from industry attendees. Following the presentation, the momentum continued: numerous distinguished experts and professors in the VCSEL field stayed for in-depth technical discussions with the Raysea team, exchanging insights on innovative applications and performance optimization of multi-junction VCSEL technology.
This showcase not only highlighted Raysea’s five differentiated core strengths but also unveiled its full-dimensional product matrix,spanning discrete, linear, and area array VCSEL and their real-world deployments across multiple sectors. As autonomous driving scales rapidly and embodied intelligence finds broader scenario-based applications, Raysea’s products will continue to penetrate into wider application fields, unlocking greater technological value and industrial momentum.
Going forward, Raysea will further increase R&D investment, accelerate the commercialization of higher-power, higher-integration VCSEL arrays, expand into emerging application scenarios, deepen global partnerships, and drive the innovative adoption of VCSEL technology in the photonic sensing industry.
