Photonic neural network chip for spacecraft. Inference using light instead of electrons.
- 860x less power than ARM Cortex-M4F (129.5 pJ vs. 111,370 pJ)
- 99.5% fidelity at 106 krad radiation
- Athermal: no active heater compensation needed
- 220nm SOI, AIM Photonics foundry compatible
Radiation model validated against ISS flight data (Science Advances 2024). All simulation done in Meep FDTD, not proxy models.
