So they have some kind of nonlinear material that can make light modulate other light, that they managed to get working at teraherz frequencies?

Sounds incredible, as in: can't believe it.

By the way, isn't Nvidia researching this?

Very real stuff (I have a PhD on this)

At milliwatt power, and terahertz frequency?

		I guess it's a theoretical limit as in the material can change properties that fast given a fast light signal.

I mean, researchers have been trying for years, what is different now?

Yes; this material is called "snake oil".

Let's see if the investors bite.

		Theranos demonstrated that they'll bite at anything.
