PreFab is a virtual nanofabrication environment that leverages deep learning to model fabrication-induced structural variations in integrated photonic devices. Our mission is to bridge the gap between design and fabrication in photonic integrated circuits.

What PreFab does

Prediction of fabrication

Anticipate how your designs will be affected by real fabrication processes. PreFab predicts process-induced structural variations: corner rounding, loss of small features, filling of narrow gaps, sidewall angle variations, and stochastic effects.

Example of PreFab prediction

Correction of fabrication

Automatically optimize your designs to ensure fabricated results match your specifications. Our correction algorithms help minimize structural variations and reduce performance discrepancies between simulations and fabricated devices.

Example of PreFab correction
