Schematic of the optical cavity with a one molecule thick layer of tungsten diselenide (WSe2) at the antinode, the point where the light field intensity is at its maximum. Credit: Deng Laboratory, University of Michigan Modern high-speed internet uses light to quickly and reliably transmit large amounts of data through fiber-optic cables, but currently, light signals hit a bottleneck when data processing is necessary. For that, they must convert into electrical signals for processing before furt...
