Israeli Processor Computes at Speed of Light

HERZLIYA, Israel (Reuters) - An Israeli start-up has developed a processor that uses optics instead of silicon, enabling it to compute at the speed of light, the company said.

Lenslet said its processor will enable new capabilities in homeland security and military, multimedia and communications applications.

"Optical processing is a strategic competitive advantage for nations and companies," said Avner Halperin, vice president for business development at Lenslet.

"Processing at the speed of light, you can have safer airports, autonomous military systems, high-definition multimedia broadcast systems and advanced next-generation communications systems."

An optical processor is a digital signal processor (DSP) with an optical accelerator attached to it that enables it to perform functions at very high speeds.

"It is an acceleration of 20 years in the development of digital hardware," Lenslet founder and Chief Executive Officer Aviram Sariel told Reuters.

The processor performs 8 trillion operations per second, equivalent to a super-computer and 1,000 times faster than standard processors, with 256 lasers performing computations at light speed.

It is geared toward such applications as high resolution radar, electronic warfare, luggage screening at airports, video compression, weather forecasting and cellular base stations.

Lenslet said its Enlight processor, unveiled at the MILCOM exhibition in Boston this month, is the first commercially available optical DSP.

"Optics is the future of every information device," said Sariel.

Jim Tully, vice president and chief of research for semiconductors and emerging technologies at Gartner Inc, said most companies working with optics focus on switching optical signals for telecommunications rather than processing information optically.

"I'm not aware of any company that has taken it to the extent of processing optically," he said.

Lenslet has raised $27.5 million so far from such investors as Goldman Sachs, Walden VC, Germany's Star Ventures and Chicago-based JK&B Capital.


The company's prototype is fairly large and bulky but when Lenslet begins to supply the processor in a few months it will be shrunk to 15 x 15 cm with a height of 1.7 cm, roughly the size of a Palm Pilot.

"In five years we plan to shrink it to a single chip," project manager Asaf Schlezinger said.

Tully said one issue is whether this technology can be produced in volume the way silicon chips are made.

"Because semiconductor manufacturing technology is well developed, you can produce millions at quite low cost," said Tully, who is not familiar with Enlight.

Lenslet said its processor will be competitive in price with a multi DSP board.

Sariel is negotiating joint projects with companies and/or government agencies in the United States, Europe and Japan to produce the processor for specific applications. It already has projects signed with Israel's Defense Ministry.

"We don't rule out licensing our technology to others," Sariel said. "We are looking at a virtual production line where production is done by others and we provide testing equipment."

Tully said semiconductor companies are working on technology that would use optical channels inside a chip to allow very high speed communication from one part of a chip to another.

"It's conceivable this technology could become mainstream inside chips in 10 years time," Tully said.

Well it's pretty obvious that light based electronics is the future, but this is the first time I hear of lasers being used. In general, light is very well suited to electronics in some ways, like the speed (obviously) and the very low heat energy loss (which reduces heating issues).

funny..its the first time I've heard it mentioned...but I can understand how it would be hard to make a laser that small! I just hope they will have figured out quantum computing soon! Imagine a computer game on a quantum computer and an organic LCD screen.....;)

That sounds exciting but I don't think it will be here soon. I would to know how they will interface everything together (storage components, graphics card, sound cards etc.
The biggest probelm hindering PC development has been among others backward compatibility & buses.
If anyone comes up with bus speeds that operate at processor speeds & all other hardware components catch up accordingly that would be enough for me.

That's a pretty big if you got there :D;)
