Agreed. It is complex but the main take away is that photonics is here to stay and that power reduction is a must! Listen to the answer to the second question about new materials.
The 45 nm from GF is what I hope we are involved with along with Ayar labs.
• GF Silicon Photonics Solutions are available on GF’s new Silicon Photonics 45nm platform which has passed critical technology milestones and is on track for full technology qualification by Q1 2022. The monolithic platform, combining RF CMOS and optical components on the same chip, includes an innovative new feature, the first micro ring resonator (MRR) optical component in 300 mm wafer technology. GF is engaged with leading customers and partners on this new platform.
