Access and cost
Get Lightmatter Passage — Pricing is not published; Passage is offered to AI infrastructure partners ahead of volume production.
Evidence it works
- Announced Passage L200 as a co-packaged optics interconnect and Passage M1000 as a photonic interposer for large die complexes. — source
- Describes Passage as a 3D photonic interconnect platform for linking dies and memory across a package. — source
What it cannot do yet
- Announced ahead of general availability, with sampling terms and pricing unpublished.
- The surrounding package, laser source and thermal design must be built around it, so it is not a drop-in optics swap.
