    This is pretty cool! So if I unplug my CPU during usage... the motherboard will shine a ray of light across my room.

    On the serious side, this IS pretty cool. Imagine the power savings it'll do! It's about time the world goes eco if you ask me.

    This is the future of computers. You can only go so fast with electronics. So you either have to move to a light-based system or Quantum computing. I'd bet in 20-30 years we will wonder how we got by with our current digital electronic based circuitry.

    This technology could apply within chips eventually, as well as between chips. Heat will drop as power requirements to maintain the communications bus drops. And the pipelines will most likely be a sealed system, such as fiber optic strands, so the whole "needs to be in a clean room" situation would be avoided.

    Couple this technology with some of the optical processor tech we hear snippets on occasionally, and the future looks bright indeed (pun intended).

    A few months ago I was wondering if they could make motherboards without using electricity, or as little as possible. Using fiber optics instead of copper wires and such in the board. Though I know its not really possible to do this without using electricity, I think everything humans are going to make rely on electricity. The reason I was thinking of this idea was that this type of chip communication is not effected by EMI. Now if only the controllers for these interfaces were somehow powered by something other than electricity.. is it possible? I dont think people can think outside that box yet.. i cant. :(

    wow fiber optics is taking over quickly, i would like to see this in cars and stuff

    Great, this is exactly the kind of technology that will create an army of Commander Data's to kill us all.

    All the tech stuff aside, that just sounds freakin awesome!!!

    Know how you feel.

    Though as a Terry Pratchett fan "I'll be more enthusiastic about encouraging thinking outside the box when there's evidence of any thinking going on inside it."

    If they can follow through with this design and take the risks necessary to set an example for other technology developers, we will see a marked reduction in electricity consumption and a more efficient future.

    let's hope the electricity providers don't start to panic and raise prices, haha!

    The rate that data transfer is increasing is wonderful. Also, the low power consumption's an added bonus. This sort of thing just makes me really happy.

    nanophotonic avalanche photodetector :D awesome name lol anyways 5 years thats around the corner! I'm looking forward to this 40Gbit/s thats fast! Thats a whole new level of gaming and mobile this could mean a lot its low powered, both phones and games system & computers that's less battery power lower chance of a system over-heating faster load times in games oh my! I'm getting excited just from typing.

    Wow. The technology is not far fetched, but I'm interested in information that has not been provided. The cascading effect seems to hint at something else for the actual data stream. If you take the video literally, it shows one clean proton in and a ton of electron garbage out with little or no control over singularities, but are stuck with pluralarities for the end result of data (lots of worthless junk code caused by lots of excessive electron cascades).

    However, I could see algorithms and formulaes being broken up and congruently run in multiple parallel within a chip or single-chip multi-processing (Multi-Core or Multi-CPU competition by a single photon-chip). On the energy side as described, only one particle (proton) is moved (energy consumption or cost) that then cascades multiple free energy particles (electrons), then the video fails to state how much free energy is actually produced (cascaded).

    Between 2000 and 2003,

    1. Bell Labs Switzerland trapped light in a silicon wafer at 15 microns and were working towards 9 microns. The best I could see from the sample wafer was a flashlight or night light that required no electricity or batteries at the time I became aware of and saw the wafer. I was curious as how it could be applied to microchips or as a true photo-chip processor or whatever type chip.

    Obviously, it's impossible to turn off, but doesn't require anymore energy introduction or conversion, if they ever develop it. The only downside I could see is if the silicon wafer cracked - the end of that. Crystal polarity and photo polarity could be used as the means of data storage and transmission without having to allow the light to escape or without having to release the excited photons.

    2. Two independent U.S. university groups trapped light within a 3 millimeter fiber optics section using 'super cooled sodium' in one university research group and 'warm rubidium' in the second university research group.

    The protons were physically stopped within the optic fiber which is the first time light had ever been reduced to 0 MPH/KPH, where as in a cyclotron light could only be slowed to about 14 to 25 MPH (about the speed of a typical bicyclist) and sped up to 6 times the normal speed of light. Light must travel at 6 to 8 times the normal speed of light to escape the gravitational pull of a typical blackhole. The cyclotron experiments is an advent to future space research satellites, if they can figure out how to miniaturize the cyclotron (LOL).

    The trapped light was easily and completely released with an introduction of a single proton. Both independent university research groups discovered that the protons contained in the trapped light automatically lined up into a dual binary system and estimated that the trapped light (protons) contained in the 3 millimeter segment of optical fiber could store well over 2.4+ kilometers of data.

    Natural physical dual-binary proton alignment of light trapped with 'super cold sodium' or 'warm rubidium'. *An attempted representation of the actual physical protons.*

    Currently, all publicly available photo electronic technologies in use do not utilize the full potential of light, other than using pulses of light for data (comparable to morse code using a flashlight), or photo polarity with crystal polarity. Electron manipulation of crystal polarity is common such as with the Junction Transister. Crystals can also be crushed to release electrons, such as with crystal-electronic lighters, etcetera.

    Electrons can also be released by bombarding a conductor, but that's generally high power with exception of naturally radioactive conductors. Millions of anti-matter (positive electrons) have been found to be created and released by bombarding gold (as small as 1 millimeter square) with a laze. A single low-power fractional second pulse laze shot at the gold created on average about 180,000 anti-matter particles per pulse. Not sure how useful anti-matter and electronic circuitry work well together at this time. :D

    I guess IBM is not using this dual-binary aspect of light. Who knows what technology is actually integrated? I need more information please, aside from the troubleshooting video chart reliant on a audio narrative. 40 Gigabits sounds more like an intentional impedence.

    I'm probably reading too much into the video, and it's probably not really a true photonic chip, but an electronic chip that uses photon bombardment of an array of photo-sensors [an element array of miniaturized plug-in photo-sensitive night lights].

    Oh well. :( Had my hopes up for the even better technology with the potential: no plugs and no batteries required.
  13. 40Gbit\s WOW imagine what`s possible when everything is tweaked.Imagine using (more?) colours !
    We can`t imagine what a leap this would be.
    Well let us hope they work fast,I`d love to see a supercomputer run on this tech.

    IBM is known to be a giant company in the IT industry.....
    Their idea is pretty good and it's gonna be fantastic one....

    Wow I don't think that they could have this product but indeed it come true......
