Duke University and Facebook’s Connectivity Lab Bring Better Optical Communications to Light

IEEE Spectrum   -   Scientific and Educational Websites

It’s a simple truth that higher frequencies can inherently carry more data than lower frequencies. The more times an electromagnetic wave cycles in a second, the faster it can be modulated to pack in information. Which is why free-space optical c...

Determining the structure of a molecule with laser-induced electron diffraction

Phys.org   -   Scientific News Websites

Light microscopes have revolutionized our understanding of the microcosmos, but their resolution is limited to about 100 nanometers. To see how molecules bond, break, or change their structure, we need at least 1000 times better resolution.
