Lightmatter Unveils Advanced Photonics Technology for AI Chips
Lightmatter has unveiled new photonics technology for AI chips, featuring an interposer available in 2025 and a chiplet in 2026, designed to boost performance through optical rather than electrical connections.
Published on April 1, 2025
Lightmatter, a Mountain View, California-based startup, has announced its latest photonics technology designed to enhance AI chip connectivity. The company, valued at $4.4 billion with $850 million in venture funding, introduced two innovative products: an interposer for connecting neighboring AI chips, scheduled for release in 2025 and manufactured by GlobalFoundries, and a chiplet aimed at augmenting AI chips, set for launch in 2026.
Supplemental research confirms and expands on these details. Reuters reported the news on April 1, 2025, while IEEE Spectrum highlighted the potential for reduced energy consumption and faster computation speeds using optical signals instead of electrical ones. These advancements are poised to significantly impact AI processing, marking an important step forward in photonics-based chip interconnect technology.
