Light Resonators Used To Move Nano-Sized Objects

timothy posted more than 4 years ago | from the tiny-stuff dept.

Science 63

ElectricSteve writes "Scientists at Cornell University report they can now use a light beam carrying a single milliwatt of power to move objects and even change the optical properties of silicon from opaque to transparent at the nanometric scale." As the article says, such an advancement "could prove very useful for the future of micro-electromechanical (MEMS) and micro-optomechanical (MOMS) systems."

Future switching? (4, Interesting)

sander (7831) | more than 4 years ago | (#30197330)

I wonder if this will be used in future optical routers and switches or even processors - if the opaque-transparent (and back) switch happens fast enough, you could easily do a very large number of parallel on-off switches to optical pathways. No need for lots of MEMS/MOMS mirrors any more.

Imagine a nanoscale thinking machines cm-5, except the light panels would then actually be part of the computation, controlling which nodes are on or off.

It's an acronym. It has no meaning, it's just an abbreviation of Micro-OptoMechanical Systems.

Researchers don't much care about recognition on /.. They're getting a Nature publication out of this so you can bet that they're fairly happy with the exposure it's getting. Although from the looks of it, it's not that uncommon for that group, damn impressive publication record. Nano, nano, nano; they've got the right buzzword [phdcomics.com] to collect high-profile publications anyway.

Less than a single milliwatt of power in a beam that moves things? Could this be the basis for the wide spread reports about telekinesis.?

Re:Telekinesis! (2, Insightful)

drmitch (1065012) | more than 4 years ago | (#30198854)

Umm... I would LOVE to see a RATE of energy production move ANYTHING. I think they meant millijoule of energy. Please don't tell me that I'm the only one that saw this.

Re:Telekinesis! (0)

Anonymous Coward | more than 4 years ago | (#30200198)

You can't talk about a milijoule laser.... lasers produce rates of energy, (well transform if you will), and they are in fact talking about a milijoule laser causing the movement. Your confusion is that the energy rate isn't in reference to the amount of energy causing the movement.

And you are properbly the only one who saw this, since most others would not make such a simple mistake in reasonning.

1 mW is just a single milliwatt? (2, Insightful)

amirulbahr (1216502) | more than 4 years ago | (#30197670)

Is it just me or does the term "single milliwatt of power" sound odd? It seems to imply something discrete that comes in ones and twos and threes and so on. Why wouldn't you just say "a 1 mW light beam"?

Now let's see if I get the -1 Off-topic that this post surely deserves.

If anything, you should be pointing the flashlight AWAY from your solar sail, in the opposite direction that you want to go in - think a rocket.

silicon nitride deformation - mirrors/light paths (1)

brindafella (702231) | more than 4 years ago | (#30198682)

Sarah, I could envisage a silicon nitride crystal (as described) having a mirrored surface attached, and being used to route light into various paths depending on the applied light pressure -- a multiple path switch. Is this possible? Does it make sense? Or, am I mis-reading what may be possible by the deformation you describe? Peter
