For PC users, the advance would mean an Internet connection nearly 1,000 times faster than broadband is today. Such an advance would mean a movie could be downloaded in minutes rather than hours, and several content streams -- like Internet-delivered TV -- could be watched simultaneously.
The communications chip NEC has developed is called a Vertical-Cavity Surface Emitting Laser, or VCSEL, which converts electric current to laser pulses, as the Newscientest.com article states. The VCSEL diode is made from "a blend of gallium arsenide and indium gallium arsenide rather than the usual aluminum gallium arsenide to be able to transfer pulses more rapidly through optic fiber". The outcome is the ability to transfer data over fiber optics at about 25Gbits/sec.
There are laser chips by NEC allready:

The laser is compact so it allows many lasers to be integrated on a single chip. The first demonstration hybrid silicon laser is only ~800 microns long. Future generations will be significantly smaller.

With this highly integrated silicon photonic transceiver, it is possible to imagine a future world in which most computing devices are endowed with high–bandwidth optical connectivity. Be they servers, desktops, or smaller client devices, all devices will have access to substantially greater bandwidth at a lower cost.
I thing is a very good concept but i dont thing it will be here for a very long time and intel will porbs chnge there minds or somehting stupid like that and give up.

I doubt they'll give up on this, as chipmakers have been looking into fiber optics for some time now - the latencies of alloys alone is reason enough to make the move.
This tech will probably start at the super-computer level and work its way down. So, you are right in this, it will probably take a very long time for us to see anything at the desktop level.
Gah.. wouldn't the ram chips need that type of speed as well?
heh.. and GPU?
I could see fiberoptic RAM becoming an actuality. If they develop this process fully, then the GPU could be made the same way (If it isn't part of the CPU by then.)

Years ago, they were talking about holographic storage. Where you could have a cube, made up of transparent (to the eye) layers which would be read in 3d by a laser. I wonder if anyone's still working on this. :?

Kinda wonder if those chips could look like the core's in that movie "IRobot".
You know.. Vikki or Sunny.
"My logic is undeniable."
I was kinda hoping it would look more like the girl in Weird Science. 8)
Amazing technology, "old" theory & dificult to implement. Anyway, it's my conviction it will be another major leap, sooner or later.
Cheers!
I hope it doesn't come too soon. My brain is getting full. I'm still trying to mentally process this:

It has also been reported
that high-K/polySi transistor exhibits severely degraded
channel mobility due to the coupling of low energy surface
optical (SO) phonon modes arising from the polarization of
the high-K to the inversion channel charge carriers [ref. 13],
and that metal gate may be more effective in screening the
high-K SO phonons from coupling to the channel under
inversion conditions [ref. 13-14]. On the other hand, the use
of high-K/metal-gate requires a p-type metal and a n-type
metal with the right work functions for high-performance
CMOS logic applications on bulk Si [ref. 15].
from a link Jack gave the other day, when I saw this "lightspeed" chip info. Now I'm reading the white paper on it. I don't think I could possibly pass up info on holographic storage - so smoke may begin pouring out my ears.
I wish I could purge old info out of my head. I can remember word-for-word the theme from The Facts of Life, but I can't even remember the point I was going to make with this post. :?
I think optical computers will pave the way for quantum state computers. What comes after that I dont know... but at that time im pretty sure Doom 3 will run ok lol
I thought the telcoms where already using fiber optic switches ? I know they are not chips but dont they process signals ? It seems to me they just need to miniturize those ?
Edit: Holy brain farts I forgot I posted already lol
Im just waiting for that vurtual reality chip. Then we can use it to create a hollodeck like in Star Trek the Next Generation. I would go in that sucker an never come out!
. o O (J/K!!)
it happens...
lol
