Terahertz radiation exists between radio and infrared. A new filter created at the University of Utah can filter out particular frequencies, a prerequisite for using it for data. The abstract of the paper in the journal Nature is freely available."

But hey, what do I know, your post is a +5, so it must be somehow insightful, not 100% redundant.

Terahertz research would seem to me to be a step in that direction, by bringing existing EM modulation techniques closer to that spectrum.
And, in the end, we're not going to want to stop there. We're going to eventually want to extend application of understood techniques to the UV bands and beyond.
It may not be effective for communicating in atmosphere, but it'll eventually be a great high-bandwidth solution for intercraft and interplanetary communications. The smaller you can make the parabolic dish, the easier it becomes to effectively focus the signal.
