Scientists Trap Light In Nano-Soup

kdawson posted more than 6 years ago | from the confusing-the-photons dept.

Science 110

An anonymous reader writes "Physicists at the Bhavnagar University in Gujarat, India have trapped light in a nano-soup concoction. The chance discovery could pave the way for lab-on-a-chip devices for processing optical information. As of now there is no theoretical explanation for why the fluid has the effects it does on laser light."

Better than flashlights or the Light of Elendil? (2, Interesting)

Jumphard (1079023) | more than 6 years ago | (#21685253)

Apologize for the rotten LOTR reference, but apart from applications to electronic this could make a really could mass light storage device. "Take this crystal with you into the (forest, cave, night, basement) and flip the switch and it will turn from darkness to light!" Sounds hocus-pocus, but cool nonetheless! Then you just charge it by leaving it in light (artificial or sunlight) and you've got another use out of it.

Re:Better than flashlights or the Light of Elendil (4, Interesting)

Daniel_Staal (609844) | more than 6 years ago | (#21685345)

Probably not: you need to keep a magnetic field of an exact strength around it to hold the light. So you still need batteries or some such to maintain the field. (You'd want an atrificial field so you can choose the wavelengths of light to capture, and because it is easier to remove uniformly.)

There is probably also a maximum amount of energy you can store per unit volume, though I'd guess they don't have that worked out yet.

If you can input more energy than is lost over time then you could conceivable build up any amount of energy until... what happens? The iron spheres melt from heat? A hole opens in the time-space continuum and the Enterprise C comes through? What?

Some physicist please tell us what happens.

Re:Better than flashlights or the Light of Elendil (3, Informative)

SatanicPuppy (611928) | more than 6 years ago | (#21687083)

In this case, the only way they're catching the light is effectively locking it up in a jar. If they open the jar to try and put more in, they lose the light they already captured.

Assuming they do find some way of adding more photons without losing what they've already got, the two options are:

1) The container fills up.
2) The container breaks.

Either way, nothing catastrophic would occur, unless they managed to contain a lot more energy. Just a flash of light. You can see from the photos in tfa, that the photons don't exhibit the same pattern that they did when the laser was firing (indicating some internal diffraction), so there wouldn't be a danger of having the equivalent of a more powerful laser shooting out in the same direction as the original beam. Then comes thermodynamics...It unlikely that they'd be able to contain energy in excess of the energy they're putting into containment (understatement), and entropy usually makes it so you have to spend a lot more energy, just to break even.

I doubt highly that you would actully get much of a laser beam out of it under any circumstance, more of a omni-directional flashlight. Now if they can use that external magnet to focus the light's direction... With quantaum fluctuations they could get around the problem of thermodynamics for the short run, maybe substantialy more so if they can work so bizzaro magic with entangled particles in a "heat sink" but I doubt there would be any hopes of seeing the NC117-C.

I'm only an undergraduate, but I made a post [slashdot.org] further down discussing briefly what I think might be happening. But basically, if my idea is correct then there is a maximum amount of light energy which may be stored in this nanofluid because there are a finite number of electrons in appropriate states for this transition to occur.

This will do great things for the National Strategic Light Reserve, which is a vital part of our national security initiatives. Specifically, it exists to protect the nation in the event the sun burns out. Up until now, we've been storing light using a series of 100 watt bulbs and mirrors, but there has always been doubt as to what would happen to our light reserves in the event of a power outage. Perhaps this technology will help us solve that issue.

The unusual fluid, they say, works at room temperature, holds photons for far longer than other systems, and can also be tuned with a magnet to store any wavelength of visible light
That is interesting. I wonder if they could extend it to trap other EM frequencies. It would make an interesting cloaking technology in my mind. Can absorb and possibly redirect radar, light, microwaves. It would seem to make decent shielding from x-rays in medical labs, who knows. I wish it said how much energy the magnetic fields took to sustain, and how many photons they can capture per area. If this turns out to be legit...

Yes: One where the math has been shown to work.

Currently they have ideas, but haven't proven the math. If the math can't be made to work, either the underlying theory is wrong, or something else is happening.

Re:No theoretical explanation? (5, Insightful)

mr_mischief (456295) | more than 6 years ago | (#21685663)

From TFA: "but the researchers believe that"

It's good to remember that "theory" and "hypothesis" are quite distinct in scientific circles. In science, a belief is not a theory. A belief is either a hypothesis that can be tested or an article of faith. Since these are research scientists and this has no clear ties to any religion I can see, I'm going to bet they'll want their hypothesis tested.

They'll want the experiment set up specifically with storage of the light in mind, since this was a surprise discovery this time. Then they'll want some way to prove, mathematically or empirically (preferably both) that the light is getting trapped consistently and how that's being done.

Then, they'll want others to repeat the experiment in other labs from their write-up and get consistent results.

Then, when scientists can use the explanation for the light getting trapped as a portion of further work and it become useful to just assume the explanation is true and move on to work based on it... then it's a theory.

Or... that's how I'd think of the words "hypothesis" and "theory" from my interested lay understanding of research science. In short, a hypothesis is an idea about something happening under certain circumstances or why something happens in those circumstances that has not been properly vetted by experiments and mathematics. A hypothesis can be right or wrong, and noone knows until it is tested. A theory is a hypothesis that has been proven reasonably correct by multiple individual teams and can be used as a basis for further work. A theory is sometimes wrong in part, like Newtonian mechanics, but should offer a good enough model to make more discoveries.

In even shorter terms, a scientist says "theoretically" only if the basis for the belief is tested and accepted. Otherwise, it's "hypothetically".

It's even mroe nuanced than that. Scientists rarely ever completely redo another's experiment, though it does happen, and in this case likely will. Often when you look at one lab's results, you can see that their results predict that other things should be true. In the case of a mathematical explanation for this phenomenon, the math will also predict that other phenonmenon should also happen. Experiments will be designed to test those predictions. If they work out, then there's more evidence that the effect is real and the understanding of the effect is real. Iterations will then continue in such fashion to evolve the technology.

explosivejared (1186049) | more than 6 years ago | (#21685335)

A rigorous theoretical explanation is yet to come, but the researchers believe that the spheres are aligned by the magnetic field and form microcavities - filled by the ferrofluid - in which the photons get trapped, resonating back and forth

I know they haven't published an explanation on this yet, but does anyone know what kind of power this sort of process takes? Power consumption would obviously be germane to computing using photons, which the article discusses. Also, what effect does the stasis have on the photon?

jericho4.0 (565125) | more than 6 years ago | (#21691306)

From the hypothesis in the article, that the varying magnetic strengths result in different size cavities to capture different wavelengths, I would guess very little power would be needed. On a chip you would only need to develop whatever gauss needed in a very small area.

I believe the author of the article is confused. A ferrofluid is a suspension of very small magnetic particles. To keep the particles from clumping, they are coated with a asymmetrical molecule, one side of which will stick to the particles, and the other side repels itself and the fluid it is in, forming a one molecule thick membrane around the particle. Commonly used substances are oleic acid and kerosene. So this is not particles added to ferrofluid, it's just ferrofluid, which makes it an even cooler discovery in my book.

Ok, I just reread that bit of the article. I was confused, it seems that this is a ferrofluid composed of two differently sized particles.

It's not just the energy. If I understand the article properly, and it works like other photon-storage schemes, the phase, polarization, etc. of the photons are also preserved, so that the light which is released is equivalent to the original light. It's possible there could be some frequency-changing effects, as in non-linear optics, but that's speculation.

Re:"Storing photons" (1)

Maximum Prophet (716608) | more than 6 years ago | (#21686349)

That's the 64,000 question. Another explaination, is that the initial laser aligns the particles, and when they turn the magnetic field off, the nano-soup creates new photons. i.e. the energy output comes from the original magnetic field, not the input laser.

If the actual photons are being stored, then it should be possible to use a femto-second laser to send a pulse into the soup, then by timing the turn-off right, get the photons to exit either in the forward direction or in reverse.

That seems like a good experiment to try. You should contact them and tell them about it. It could save them a lot of time and money.

If it does turn out to just be storing energy, it would be interesting to see why it is converted back into photons of the same wavelength when the field is turned off.

On the other hand, if it is just refracting the light, I could imaging this being used to create a sort of DRAM for photons. The reason I say DRAM is because I imagine it would have to be refreshed in order to replace photons being absorbed. That is, unless you could find a way to have the storage mechanism automatically replace/duplicate lost photons in a way similar to semiconductor lasers.

I wonder if this effect has anything to do with the hyperfine structure exhibited by electron orbitals in atoms. In a magnetic field, the energies of spin-up and spin-down electrons will diverge slightly, revealing hyperfine band structure.

In an atom there are also forbidden energy transitions and metastable states. Maybe in the presence of a magnetic field the hyperfine structure of these nanoparticles causes new metastable states to arise in the structure of the molecule. Then, light of a particular frequency triggers an electron transition to a metastable state, which becomes an unstable state when the magnetic field is switched off. The electron then simply transitions to its base state releasing a photon of the same energy. This might be how light is "trapped" in this nanofluid.

A question... (0)

Anonymous Coward | more than 6 years ago | (#21685885)

If I was viewing the universe from the perspective of the beam of light, would I observe the passage of time once it had been halted? I mean, theoretically time seems to stand still when traveling at the speed of light, right? So if I were somehow to 'ride the light' and it stopped, then I guess I would start observing the passage of time. Would I notice a change?

ajdecon (233641) | more than 6 years ago | (#21686155)

Except that according to TFA, the light hasn't actually "stopped". Instead it's been trapped in resonators, so in a crude picture it's bouncing back and forth within the fluid. The time effects observed relative to light should remain as they usually are, per relativity.

macromaniac (1140721) | more than 6 years ago | (#21689384)

that would explain why they were still able to see the light when the laser was turned off; photons have to reach your eye to be seen, which makes me want to ask how long this fluid is able to internally refract light = /

I don't even understand how, if no time passes for a photon, how it can be created, destroyed, and bounced off stuff. Since position and direction can change despite the frozen status of the photon, doesn't that imply that those are not purely traits of the photon itself?

This should not come as a surprise that this amazing find happened in India. After all, this is the land where the Vimana [wikipedia.org] flying machines were created thousands of years ago, and also where the first nuclear war [zenzibar.com] occurred, long before the Roman empire existed.

Photon computing... not quite there (1)

BlendieOfIndie (1185569) | more than 6 years ago | (#21687836)

I'll accept that you can transfer information using photons. However, using this technology, magnetic fields are still required to store the photons. Hypothetically, if a computer was build using this nano-soup, then it would only be a hybrid-photon computer. Any ideas on what a photon computer buys you (technologically speaking). In copper wire, light travels slower than the speed of light in a vacuum (about 2/3c). But presumably the magnetic fields are created using standard electrical principles (like winding an iron nail with copper wire (to make an over simplification)). If the magnets are based on electricity, then it seems like this would limit the benefits of a photon computer. I guess it took decades to make a computer out of transistors. Maybe in 30 years there will be photon computers. I picture rooms filled with cans of photonsoup, and lines of people waiting with punch cards (deja vu?). Seriously, though. Does anyone have ideas pertaining to the first two paragraphs?

Store electrons? (0)

Anonymous Coward | more than 6 years ago | (#21688002)

From the article:

For over a decade scientists have been working towards light-based computing: where circuits control photons - particles of light - in the same way that they currently manipulate electrons. [...] Any microchip designed to process optical signals has to store photons, perhaps by slowing or trapping light in carefully designed crystals.


Maybe I'm wrong (which is very likely) but since when do computer circuits/chips store electrons?
