Automated "Inverse" Design of Grating Couplers for Co-Packaged Optics
How we design grating couplers for co-packaged optics with shape optimization and adjoint gradients, with a worked dual-layer example and measured dual-layer couplers from an OFC 2026 paper we co-authored with TSMC.
Case Study
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.
