* https://youtu.be/29aTqLvRia8?t=714 <GlobalFoundries> seems to be one of the leaders at the time. E.g. <quantum computing> company <PsiQuantum> uses them. Part of this was from acquiring <IBM>'s microelectronics division in 2014.
* https://youtu.be/t0yj4hBDUsc?t=566 mentions the paper <Deep learning with coherent nanophotonic circuits>

As of 2025, this company was by far the most well funded in the field.

It was founded by some of the authors of the influential paper <Deep learning with coherent nanophotonic circuits>.

Presented e.g. at https://youtu.be/t0yj4hBDUsc?t=456 from <video Silicon Photonics: The Next Silicon Revolution? by Asianometry (2022)>.
