Fidelity-Aware Optimisation Framework for Electromagnetic Simulation in Integrated Photonics
Year: 2026
Type: conference-paper
Abstract: Electromagnetic optimisation of silicon photonic components based on fixed high-accuracy simulations is computationally inefficient, especially for designs involving many variables. This work presents a multi-stage, multi-fidelity optimisation workflow in which numerical accuracy is treated as an explicit design parameter. Low-fidelity simulations are used for global design space reduction, while medium- and high-fidelity simulations are reserved for local surrogate-driven optimisation and validation, respectively. Representative 3D FDTD results for a silicon waveguide crossing demonstrate substantial computational savings without compromising the final design accuracy.
