The terahertz gap is a range of electromagnetic radiation between microwave and infrared that is very hard to generate and receive because it is too low frequency for optical systems but too high frequency for electrical.
By my reading this isn't a new way to generate THz signals, but a way to modulate light with existing THz signals.
I did not read the article but I sure do love to say “Plasmonic Modulator”.
Sounds like something from Doctor Who.
Or a component of a retro encabulator.
it is even by Matthew S. Smith
which is pretty close...
Definitely a component on a warp engine, near the coil inducers.
In my head, I hear Marvin the Martian saying it. Especially if it’s made of Illudium Q-36.
some these ai data centers would be using gama rays haha
