New metamaterial-based strategy to combine and transmit multiple light modes

https://phys.org/news/2023-09-metamaterial-based-strategy-combine-transmit-multiple.html

"unprecedented data rates especially in fields where large-scale parallel data transmissions and computations are common... light-mode nanowire coupler carrying total multi-mode signal injects desired light mode into bus waveguide or extract one from it sending towards different path... high coupling coefficient... cascading multiple couplers supporting 16 different light modes...  2.162 Tbit/s data transfer rate... easily scalable and compatible with current fabrication... large-scale neural networks, and quantum communications"
