Fiber to the home is needed now. I would much rather have all of my services such as phone, internet, and cable comgin over one pipe. This would require more bandwitdh than you can get over a coax cable, I beleive anyway.
This new form of incandescent would be even more expensive than LEDs for quite awhile. The making of photonic structures is very time consuming and resource intensive., therefore LEDs will most liekly be the short term winner in cost.
1) Conventional traffic lights have to be replaced once a year to make sure they are working, whether they have died or not. LED based traffic lights last up to 10 years.
2) Conventional traffic lights use colored glass to filter the broad spectrum light into the desired color, wasting large amounts of the generated light. LED based lights do not require a filter so the power savings are huge.
Probably the biggest application for this technology will be optoelectronic integrated circuits. One of the things that makes optical communications so expense and limits there speed is the need to convert from a light signal to an electronic signal and vice versa. Not only are electronic cictuits slower than there optical counter parts, all the separate modules are expensive. This technology would reduce the need for conversion, at least part of the time, by allowing one to make optical circuits instead. Once that can be done, integrating the wave guides, pump lasers, and amplifiers would be not too far down the road. This could make fiber to the home a reality.

A few points:
1) Light has zero mass.
2) All quantum mechanics tries to do is describe how these thingies interact, not what there appearance is.
3) A particle does not necessarily have unique properties. As I said previously, two bosons can have the exact same properties and still be different particles. They *appear* to be the same particle because they have the identical properties and are therefore indistinguishable (sp) from each other.
4) Atoms are made of particles. The Bose-Einstein condensate you describe is made of many atoms. Although they are all in the same state, they are still many particles and they just react in unison to external stimuli. You could actually probe each individual atom but you could never tell any one atom apart from the others since they all "look" alike.
5) We indirectly see quantum particles all the time. However, our interaction with them is completely classical on our scale. Therefore calling them quantum particles doesn't make much sense. A baseball is made of quantum particles and can be seen by the naked eye. However, it behaves classically and I don't believe anyone woul call it a quantum particle.
6) Absolutely true, no one truly understands the meaning of quantum mechanics. However, it is possible to understand the machinery of the theory and apply it to problems. Understanding how the results come about is not the same thing as understanding why the theory is correct, besides its mathematical correctness etc.
Thanks for your time...

Actually, the energy, and photon, are stopped by the medium since the light is absorbed. The original photon itself is never restarted, just one that looks like it.

Your are right that the result is essentially stopped light but you have something a little wrong.
Photons are bosons. Two bosons *can* have the same properties. Since the photon that is emitted by the medium has the same properties it appears that the light was actually stop by the medium. The inability to disguish between two photons in the same state is what makes it appear that the light has stopped.
Fermions, such as electrons, cannot be in thesame exact state at the same time. The reason for this comes from the Pauli exclusion principle not the uncertainty principle.
The teleportation effect has to do with entanglement of photons, which is something I know little about but the process is very different.
Hopefully I haven't made any mistakes here, please correct me if I have.
Wouldn't that fall into the same category? Supply vs. demand would determine the ability for an employee to bring money into the company, wouldn't it? Maybe I'm missing your point.
IANAE (E=economist or whatever), but it seems to me, at least in the US, that salary is based on the potential for bringing in revenue for the company. I realize there are many other factors too, but this seems somewhat common.
Even though someone may work much harder in some sense than another, it depends on the product/service for sale by the company.
So what if P2P was shutdown. How many people were using P2P networks to download software in 96/97? Not many. Besides, what about IRC and regular old FTP? They don't get shutdown do they? Seems to me that wouldn't stop anyone if they really wanted something.
On my campus (UMass) they only stop serving things like DVDs. As long as you don't serve large amounts of data, they do nothing.
This post was not meant as a flame, just criticism. Thank you for your time:).
But aren't MS's business practices why they are in this position? If they weren't trying to screw everyone else over, would the code be this cryptic mess that is unfixable?

It's like saying someone who goes to prison for murder (and fucked:)) doesn't deserve the punishment according to the law. Granted the law doesn't specify the punsihment here, but the judge will.
Red lasers were very expensive too, before CD players. Once the CD player became relative wide spread, the price dropped. Like most technology, this is the typical cycle. All knew stuff is expensive until the demand increase enough that the production cost can be spread over enough units to bring the single unit cost down. It will happen with blue laser based electronics also.
That used to be true. Nichia (of Japan) has been sampling bluew lasers with lifetimes of 10000+ hrs., the minimum for most applications. Once they are in use, their cost will come down.
Not to criticize you post, because I agree, but Electrical engineers are not certified. There is no certification process besides the Bachelor's degree that is required, or even available I believe, in order to work. I think Civil and Mechanical do require something depending on the type of work.
I agree though, some formal certification/education program should be developed for general system administration and especially for security specialists.
Talk about taking away your basic rights as a human. It's like the government saying, "We can't trust the common person to not commit murder. Therefore, we must place everyone in prison. That is the only way to protect the innocent."
How does that make sense?
It is basically takign away everyone's right to make moral decisions about how to conduct their lives. You can't tell me that doesn't violate the constitution/bill of rights somehow.
Most likely IBM will try to liscence the technology to other chip makers. By the time that is ready to happen who knows what Dell, etc. will put in their machines.
I'm not sure but I think you might be confusing pulse spreading (in time) with homogeneous broadening (in wavelength/frequency). The former occurs since shorter wavelength light travels faster than longer wavelength light in a medium other than air. The latter results from the finite transition width (in wavelength) of the source. this is probably more confusing. I think I'm not understanding you though, oh well.

FYI: The real part of the refractive index for metals is, in general, less than 1.
producing the structures is one thing, incorporating them into light bulbs is a whole other matter...

Here is two reasons why the savings are so big:
1) Conventional traffic lights have to be replaced once a year to make sure they are working, whether they have died or not. LED based traffic lights last up to 10 years.
2) Conventional traffic lights use colored glass to filter the broad spectrum light into the desired color, wasting large amounts of the generated light. LED based lights do not require a filter so the power savings are huge.
