PicoJool to sample first VCSELs in Q2

The 200G VCSEL products pave the way for optical links as inexpensive, compact and manufacturable as traditional copper connections, with a clear roadmap to 800G, 1.6T and 3.2T.

The company integrates its optical chips into massively parallel pluggable modules targeting large-scale AI systems. Underpinning the effort is a manufacturing partnership with WIN Semiconductor, the world’s leading VCSEL producer for 3D sensing applications, which has shipped more than a billion chips over the past decade.

PicoJool’s 200G designs and process recipes have already been transferred to WIN Semiconductor, the Taiwan compound foundry, and other foundries, all of which specialise in GaAs. Because GaAs-based VCSELs are unconstrained in production capacity, PicoJool avoids the supply bottlenecks that limit competing laser technologies.
