To build their new resonators, Feng and colleagues carved circular cavities 3-5 µm in diameter out of a layer of silicon oxide on silicon chips, and then placed flakes of graphene across the ...

Bowtie resonators that build themselves bridge the gap between nanoscopic and macroscopic Date: December 6, 2023 Source: Technical University of Denmark Summary: Two nanotechnology approaches ...

Built into a commercial CMOS chip combining light in electronics, to enable scalable integration for next-gen computing.

Acoustic-wave resonators have become the leading technology, because they have the right range of properties to determine the optimal filter that can be derived for these applications. 5G devices ...

The resonators are cooled to well below 1 K and the experiment begins with a blue laser pulse being fired into the interferometer, which creates vibrations in one of the resonators. This vibrating ...

Researchers at Harvard University in the US have made the first ultra-high-quality micro-ring and racetrack resonators from lithium niobate. The new devices, which consist of plasma-etched ...
