DEMO Spring: Quantum Dots About to Move into Camera Sensors

When I scanned through the exhibitor list at Demo Spring in Palm Desert, Calif., InVisage Technologies, a company promising a leap forward in camera sensor technologies with paint-on quantum dot technology, immediately went to the top of my "gotta check this out" list. I was even more intrigued to discover that their Chief Technology Officer, Ted Sargent, had written an article for IEEE Spectrum's February issue explaining the technology. ("Connecting the Quantum Dots.") He hadn't happened to mention that he had a little company about to introduce image sensors into the cell phone market.

Two Startups Are Bringing Fiber to the Processor

Avicena’s blue microLEDs are the dark horse in a race with Ayar Labs’ laser-based system

Diffuse blue light shines from a patterned surface through a ring. A blue cable leads away from it.

Avicena’s microLED chiplets could one day link all the CPUs in a computer cluster together.

If a CPU in Seoul sends a byte of data to a processor in Prague, the information covers most of the distance as light, zipping along with no resistance. But put both those processors on the same motherboard, and they’ll need to communicate over energy-sapping copper, which slow the communication speeds possible within computers. Two Silicon Valley startups, Avicena and Ayar Labs, are doing something about that longstanding limit. If they succeed in their attempts to finally bring optical fiber all the way to the processor, it might not just accelerate computing—it might also remake it.

Both companies are developing fiber-connected chiplets, small chips meant to share a high-bandwidth connection with CPUs and other data-hungry silicon in a shared package. They are each ramping up production in 2023, though it may be a couple of years before we see a computer on the market with either product.
