University of Rochester develops electro-optical modulator in LN
Researchers at the University of Rochester developed an electro-optical modulator using a thin film of lithium niobate (LN) bonded on a silicon dioxide layer. The resulting electro-optical modulator is described as the smallest such device ever created, potentially paving the way for large-scale LN photonic integrated circuits.
The modulator project builds upon the lab’s previous use of lithium niobate to create a photonic nanocavity—another key component in photonic chips.
The research is supported by the National Science Foundation, Defense Threat Reduction Agency, and Defense Advanced Research Projects Agency (DARPA). Fabrication of the device was done in part at the Cornell NanoScale Facility.

You just read about All. A technology from the archive that helped get us here:
Google/Alphabet Project Loon served 2011–2021. What ultimately replaced it?
Google/Alphabet Project Loon solar-powered balloons drifting in the stratosphere (~20 km), steering by rising and falling into different wind layers, relaying LTE from ground stations to phones far below. Its job passed to Unit economics — but the problem it solved, and the ideas it proved, live on in what replaced it. The standard rests here in the archive. One of 198 technologies here that opened a door and then held it for the next.
