Now for an all-optical transistor and away we go!

Anything's a diode if you're bright enough.

What about the transtator?   I can't wait for the Iotians to reverse-engineer one!

dionysusaur: Now for an all-optical transistor and away we go!


Eventually we might have multiple machines running on the same hardware using different wavelengths of light.

/stay away from the brown laser

tag is understatement of century.

This seems really cool. Unfortunately I know just enough about this to know that I really don't understand the implications.

The Red laser is where I keep all my pr0n.

Quantum computing power weeeee

LOL nice. I heard "syl-a-cone die-ode" in his voice the second I read the headline.

/just an overgrown pile of microchips...

Multiple wavelengths resonating in one finely tuned ring?  Cool, if possible.

I read the headline as "silicon dioxide" for some reason.  WTF? We've got plenty of rocks and sand.

It's pretty easy to make, too - just vent a bottle of silane...

And right below it is an article from 2011 about pretty much the same thing. (Diagram)

I thought that required Celinium?

It means we're just a couple of components away from being able to build a light-based computer, instead of telling on electrons. I'm not a physicist, but it seems that this will counter some of the problems we're running into with further miniaturization. Because at this point, things are so small that we're running into issues where electrons in different channels are interfering with each other.

Sounds a lot like waveguide theory.

Magic in action.

The catch is that (for purposes of this kind of thing), a photon is "bigger" than an electron. So an optical diode like this takes up much more space on a chip than something comparable on a standard IC.

Storing light.
They could be on to something brilliant.
