Technology

Compute at the speed of coherent light.

The P3DX Engine replaces electrons with photons for AI's most expensive operation — large-matrix convolution — using energy-free optical Fourier transforms.

'Winning' features

  • Energy-free Fourier transformation

    Photonics performs Fourier transforms as a passive optical property — no energy cost.

  • Convolution scaling: O(N²) instead of O(N⁴)

    Reduces the fundamental complexity of the operation at the heart of modern AI.

  • CMOS-compatible integration

    Manufactured on standard silicon photonics processes with proven PDKs.
