[PCW] New Anti-laser Tech Paves Way for Optical Computing

Yale University scientists have built what they call the first anti-laser, a device that can cancel out beams of light generated by a laser.

Such a device could be an integral element in optical computers, a long promised successor to today's computers that would use light instead of electrons to process information.

While scientists have long known of different ways to absorb light, this work is unique in that can absorb light of a particular wavelength, the researchers claim.

"After some research, we found that several physicists had hinted at the concept in books and scientific papers, but no one had ever developed the idea," said Yale University physicist A. Douglas Stone, who along with fellow researcher Hui Cao led a team of researchers to build the anti-laser. The device was based on the theoretical work Stone published last summer. A summary of their work appears in the Feb. 18 issue of Science.

==============================

Such an anti-laser switch could help solve one of the toughest challenges in building an optical computer, namely the management and manipulation of the light used to encode information. For instance, a CPA could be used in an optical switch, one that would absorb light of a particular wavelength while letting light with other wavelengths pass. It could also be used to detect incoming light, or as a waveguide to direct beams of light along certain routes.

That could lead to optical switches replacing transistors in future computers.

Optical Computing, I cannot wait!

You and many more of us, but this technology will not be cheap....

Just like when computers first came out, not cheap...

A revolution on this scale, with uber fast data transfers and possibly new computing research advancements, we may be soon using Super Computers capable of streaming anything on a network real time & computing 500 Tera Flops a second.... (I can dream right?)

Need to download 50 GB? Give me a few seconds, All done!

The first thing they need to make is an Optical Drive & an Adapter card to make it work! PCI x32!!!

what will happen to PC gaming if this is available for next gen consoles? PCs will no longer have anything to stand on. I mean, light is as fast as it gets.

I think you have that backwards....

PC Gaming will be SMALL & Computers will be SMALL....

There will be an All In One Device...

Me bets it will be something along the lines of an iPad & xZoom..

Controls would integrated into into side bezel, the mouse will be history (Touch Only), just like the console...

You only need to look at the PSP2 to see where this is going..

Keep an open mind, dream, and be smart...

thats what I'm saying. I love my desktop. I love my keyboard and mouse. I dont want to play an FPS or RPG with touch screen. I cant imagine that being a good experience at all. The only type of game I could see benefiting from touchscreen would be RTS.

And where this would take us aside, assuming consoles keep their controllers and pcs keep our keyboard and mouse, what will give us PC gamers the edge technology wise? I feel like this technology would hit a wall very fast. We wouldn't have new graphics cards coming out every 6 months. We wouldn't need new processors. once you make a graphics card that can process data at the speed of light, theres no going up. It'll be some major processing power, but we wouldn't have a stool to stand on against consoles like we do now. And developers are already showing their love for consoles. Some like to push the boundaries of technology for PC, but once this tech is available I don't think we'd be getting any love.

Touch Screen RPGs would be fabulous, as I code for RPG games, it's extremely easy to make menus which are touch screen controlled...

But, I suppose eating & Playing at the same time would be out of the picture...

Just make a stand for the touchscreen (on the back of it), and have USB Ports to make that possible, no biggy... add Keyboard & Mouse...

I think there is some confusion here. This wouldn't create a "speed ceiling". Calculations wouldn't take place "at the speed of light" anymore than current ones take place "at the speed of electricity".

Computers don't get faster because we find ways to speed electricity up. Their will still be frequency, architecture improvements, latency reductions, bandwidth increases, and so on with light.
