The Virtual Nanofab
PreFab simulates photonic chip fabrication with foundry-accurate process models. Predict lithographic effects, etch bias, and process variation before tape-out. Eliminate design-manufacturing iteration loops and accelerate development with fab-aware optimization.
From Design to Fabrication Prediction
Most photonic designs fail on the first fab run. PreFab predicts how your design will actually look after manufacturing, capturing lithography, etching, and process variation from real foundry data.

Fabrication-Aware Design
Beyond prediction, PreFab integrates manufacturing constraints directly into your design workflow. Our differentiable models enable fabrication-aware optimization, from verifying optical performance with realistic geometries to inverse design that optimizes for post-fab outcomes.
Optical Simulation with Predicted Geometry
Use PreFab's predicted post-fab geometry in your optical solver to simulate realistic device performance. Capture fab-induced effects like broadened resonances, wavelength shifts, and loss before tape-out.

Pre-Compensated Designs
Automatically adjust your input geometry to compensate for known fabrication biases. PreFab's corrector model pre-distorts designs so the manufactured structure matches your target specification.

Inverse Design and Optimization
Optimize for post-fabrication performance using PreFab's differentiable models. Run gradient-based inverse design workflows that account for manufacturing constraints from the start, designing geometries and topologies for real-world outcomes.
