Although the detection of optical beams carrying angular momentum have been explored with nanophotonic methods, the metrology of optical angular momentum has been limited to bulk optics. We demonstrate angular-momentum nanometrology through the spatial displacement engineering of plasmonic angular momentum modes in a CMOS-compatible plasmonic topological insulator material.”
Twisted Light Could Dramatically Boost Data Rates https://spectrum.ieee.org/telecom/wir... “Big deal, you say? It most certainly was. The concept of orbital angular momentum (OAM) has done nothing less than inspire a reimagining of what we’re capable of doing with electromagnetic radiation. Beams that carry OAM can be used to move tiny objects, and they have been used to enhance the resolving power of microscopes.”
What is the internet? 13 key questions answered https://www.theguardian.com/technolog... “One measure is the amount of information that courses through it: about five exabytes a day. That’s equivalent to 40,000 two-hour standard definition movies per second.It takes some wiring up. Hundreds of thousands of miles of cables criss-cross countries, and more are laid along sea floors to connect islands and continents. About 300 submarine cables, the deep-sea variant only as thick as a garden hose, underpin the modern internet. Most are bundles of hair-thin fibre optics that carry data at the speed of light.” ____________________
