Learning Auto-Routing by Building: From Brute Force to an Auto-Design Agent
How I learned auto-routing for photonic chips — a failed brute-force attempt, AI as a learning partner, interactive HTML arenas, a PhotonForge router, and an agent that iterates 27 designs in under three minutes.
Predicting Peak Memory for an Electromagnetic Mode Solver
How we replaced a heuristic memory estimate with a calibrated model for Tidy3D mode solver workloads, eliminating under-predictions across the calibration set.
Can AI Agents Autonomously Design Components on Photonic Chips?
We gave AI agents a photonic simulator, a DRC engine, and four design challenges. They autonomously designed waveguide bends, crossings, splitters, and demultiplexers — some reaching near-perfect performance.
Designing a Photonic Chip Component with ~45 Lines of Python
A compact introduction to photonic inverse design with Tidy3D, using a pre-built simulation and a ~45-line optimization loop.
