About
Prismarch builds co-packaged optical interconnects for AI clusters. Our silicon-photonics transceiver moves 1.6Tb/s between accelerators at 3.5pJ/bit — a fraction of the energy of copper or pluggable optics.
The team spun out of the photonic integration group at TU Eindhoven. We tape out on a commercial foundry PDK, so our path to volume runs through existing fabs, not a new one.
First silicon back from the foundry — full link demonstrated at 800Gb/s. Evaluation agreement signed with one hyperscaler. Two granted patents on the modulator design.
