Advancing Photonic Inverse Design with Interpretable Machine Learning

Advanced Photonics Research, Volume 7, Issue 5, May 2026.
The work applies the interpretable machine learning technique called LIME (local interpretable model‐agnostic explanations) to the inverse design of photonic chips, revealing hidden optimization patterns and guiding better starting designs. Using insights from LIME improves performance of two‐mode multiplexers, showing interpretable methods can ...
