Optical Computing: Principles, Examples, and Prospects

Tutorial presentation on optical computing given at the conference Optical Fiber Communications (OFC) in San Francisco on 3 April 2025.The material in this presentation is largely drawn from the Perspective piece on optical computing published at https://doi.org/10.1038/s42254-023-00645-5 (open-access preprint: https://arxiv.org/abs/2308.00088) in 2023, but the presentation contains only a subset of the paper's content. However, the presentation does also contain some examples that have been published since the original Perspective appeared in 2023.
