Twisted lights in the sky

Twisted light.  Polarized in a new and different way?  Or a way I just never heard of?  Really?  Or maybe it’s just a new application of circular polarization?  Not sure.  But anyway, 2.5 terabits of information a second would be nice to have for communicating in space, between probes and the homeworld.  Between homeworlds in the cosmic civilization-scale jetlag.
