Lumentum Unveils VCSEL Scale-Up for AI, Challenges Photonics Dominance
Event summary
- Lumentum demonstrated a new optical interconnect solution at OFC 2026 utilizing VCSEL technology.
- The solution targets AI infrastructure scale-up, specifically addressing bandwidth, power, and integration challenges.
- The platform integrates 1060nm VCSELs and photodetectors in a monolithic array with backside lens technology.
- Lumentum has shipped over 10 billion VCSEL emitters to date, leveraging existing high-volume 3D sensing manufacturing.
- The solution offers an alternative to silicon photonics and InP laser-based architectures.
The big picture
The increasing bandwidth demands of AI infrastructure are exceeding the capabilities of traditional electrical interconnects, creating a significant market opportunity for optical solutions. Lumentum’s move to leverage VCSEL technology, built on its existing 3D sensing manufacturing base, positions it to challenge the dominance of silicon photonics and InP laser approaches in this critical segment. This represents a strategic diversification beyond Lumentum’s core optical components business.
What we're watching
