Abstract Scope |
Machine learning and AI have seen tremendous adoption in design and
manufacturing in recent years. We aim to utilize machine learning and AI to obtain optimum designs for multi-functional photonic structures governed by electromagnetics coupled with manufacturing constraints. Machine learning-generated designs enable a new optimization approach that is less prone to falling in local minima than gradient-based optimization. Inverse design tools and topology optimization often yield complex structures in the electromagnetic domain that can pose a learning challenge for the neural network. To remedy this issue, we demonstrate an efficient optimization technique that reduces the training samples' complexity and enables higher-quality predictions from the neural network. Additionally, by training a neural network over a large pool of multi-physics parameters and manufacturing constraints, we can demonstrate a rapid design exploration environment for complex designs that would otherwise be computationally expensive to carry out using traditional gradient optimization and design tools. |
