PALO ALTO, Calif. — PicoJool, a Silicon Valley startup focused on optical connectivity for AI infrastructure, introduced a family of 200G Vertical Cavity Surface Emitting Laser (VCSEL) products with bandwidth exceeding 37GHz. The company plans to begin sampling chip-level products next quarter, including quad 100G, quad 200G, and 32x50G NRZ micro-VCSEL devices aimed at scale-up AI networking architectures. PicoJool said it is already collaborating with hyperscalers and system startups on next-generation pluggable optics, near-packaged optics (NPO), and co-packaged optics (CPO) designs.
The announcement addresses one of the key questions facing AI infrastructure designers: whether VCSEL technology can continue scaling to support the bandwidth requirements of future GPU clusters. PicoJool says its architecture provides a roadmap from current 200G devices to 800G, 1.6T, and eventually 3.2T optical links while maintaining the low-cost manufacturing characteristics that made VCSELs the dominant technology for short-reach data center optics. The company combines parallel optical architectures with advanced packaging techniques and plans to integrate the technology into high-density optical modules for AI systems.
PicoJool is manufacturing its devices through a partnership with WIN Semiconductor, a major supplier of gallium arsenide (GaAs)-based VCSEL technology that has produced more than one billion chips for 3D sensing applications. The company said its 200G designs and process recipes have already been transferred into production environments at WIN and other compound semiconductor foundries. PicoJool expects high-volume manufacturing ramps to begin in early 2027.
• Introduced 200G VCSEL products with bandwidth exceeding 37GHz
• Sampling planned next quarter for quad 100G, quad 200G, and 32x50G NRZ devices
• Target applications include pluggable optics, NPO, and CPO for AI clusters
• Uses GaAs manufacturing infrastructure rather than silicon-based laser processes
• Manufacturing partner WIN Semiconductor has shipped over one billion VCSEL chips
• High-volume production expected in early 2027
• Technology roadmap extends toward 800G, 1.6T, and 3.2T optical links
“We are excited to enable many optical transceiver and hyperscale companies to meet the growing demand for scale up optical connectivity solutions with an exciting product line and roadmap,” said Al Yuen, founder and CEO of PicoJool.
🌐 Analysis
PicoJool’s announcement is notable not only for the claimed 200G VCSEL performance milestone but also because of the credibility of the team behind the company. Founder Al Yuen has been involved in multiple generations of VCSEL-based networking products dating back to Gigabit Ethernet deployments in the 1990s and has contributed to advances in active optical cables and high-volume VCSEL manufacturing. The company’s strategy centers on leveraging the mature GaAs manufacturing ecosystem rather than relying on newer laser technologies that may face scaling or supply-chain constraints.
Pat Gelsinger’s involvement adds another layer of industry significance. Gelsinger serves as a General Partner at Playground Global, one of PicoJool’s investors. He previously spent more than three decades at Intel, where he became the company’s first CTO and later CEO from 2021 to 2025. Before returning to Intel, Gelsinger led VMware for nearly a decade, overseeing its expansion into cloud infrastructure and enterprise software. Throughout his career he has been closely associated with major platform transitions in computing, from x86 processors and virtualization to AI infrastructure.
