Lightwire, the first fully chip-integrated optical interconnect, is designed to push modern compute faster, denser, and farther.
The fastest chips shouldn't be constrained by their slowest connections
Modern compute is bottlenecked by the connections between its chips, not by the chips themselves: memory limited to one row deep on each side of the GPU, layouts forced around signal length, and standards tangled between millimeter and meter.

performance from a millimeter to a meter
Lightwire moves data from a millimeter inside a chip to a meter across a rack. One link, one standard, holding chip-internal performance across the entire chip-to-rack range.
Designed to drop-in
Lightwire directly replaces electrical wires at more than 600 per millimeter inside the same interposer that already connects GPUs to high-bandwidth memory. No new packaging, no new assembly step, just new architectural freedom.
Optical interconnects: built-in, not bolt-on
Optical interconnects
Built-in, not bolt-on
Lightwire is fabricated as a new layer in silicon, on the same wafer lines that already produce modern chips. The optical layer is part of the chip itself, inheriting silicon's yield, density, and economics from day one.
