Exciton Labs Visible-light compute

No clock.Just light.

An AI processor that computes by interference instead of switching. The answer forms while the beam crosses the chip.

Live interference field
Passive
The heavy math costs almost no power
Parallel
Many streams share one physical path
Nonlinear
Decisions get made without leaving the light
Self-routing
The chip rewires itself around the workload
Inside

Five layers.
One beam.

Layer one

Encode

Incoming data is written onto the beam itself. From this point forward, nothing in the pipeline is electronic.

Layer two

Interfere

Beams cross. Where waves add and cancel, the result already exists. Nothing is computed โ€” it arrives.

Layer three

Decide

Light meets matter and becomes something that can push back. One beam blocks another. That is a decision, made without ever converting to electricity.

Layer four

Route

Bright beams bend the medium they travel through and carve their own channels. The chip reshapes itself around whatever it is currently doing.

Layer five

Remember

The finished pattern is frozen into a crystal and read back indefinitely. Memory that holds its state with the power off.

The argument

Compute you
don't pay to run.

Conventional silicon$1,260,000/yr
Exciton engine ยท same workload$11,300/yr

The heavy math is passive, so there is almost nothing to cool. The one part that genuinely wears out is a module you pull from the front of the rack and replace in the field.

Where we are

First light is a scheduling problem, not a miracle.

Every fabrication step this needs already runs in commercial foundries today. What's left is yield. We're looking for foundry partners, photonics engineers, and the first workload worth putting on it.
