Twisting light to enable high-capacity data transmission

Article wrote:
For the first time, researchers have used tiny gears made of germanium to generate a vortex of twisted light that turns around its axis of travel much like a corkscrew. Because germanium is compatible with the silicon used to make computer chips, the new light source could be used to boost the amount of data that can be transmitted with chip-based optical computing and communication.

It appears they're using tiny gear-like Germnanium structures atop standard microprocessor transistor tech to enable a new kind of data transmission, which should be much faster than current electron tech. Of course, this is the charge field in action.

There's a longer paper at the bottom, with lots of diagrams and some photos of the structures. Perhaps we could model them ourselves and see how things look?
