IBM HOLEY OPTOCHIP PDF

IBM Researchers have built an optical chip that can transfer more data per second than pretty much anything else on the planet. They call this transceiver the Holey Optochip — holey because they've taken a chip wafer and fired 48 holes in it so that laser light can be blasted in and out of the chip, moving data at one trillion bits per second. It doesn't use much power either — just under five watts. That's a big issue in today's data centers and supercomputer installations. IBM doesn't plan to turn the Holey Optochip into a product, but they would like it if someone in the transceiver business licensed their technology to build super-fast networking technology for high-performance computers.

Researchers at IBM have created an optical computer chip that can transmit and receive data at up to one terabit per second 1Tbps.

The chip, dubbed the Holey Optochip, is basically a conventional silicon chip with 48 holes drilled into it pictured above , and an array of lasers and photodiodes on the back pictured below.

Each hole allows a laser beam VCSELs; vertical-cavity surface-emitting lasers to pass through from the beneath the chip to the switching circuitry on top, and then back down to a photodiode, effectively creating a channel optical transceiver. Each channel is rated at 20Gbps, for a total bandwidth of Gbps.

The chip is primarily of importance because it has been built using a standard 90nm CMOS process; these chips could be found in your computer within the next year or two. As processor performance increases, optical interconnects between CPUs are the next logical step. This site may earn affiliate commissions from the links on this page. Terms of use.

IBM Holey Optochip is first to 1 trillion bits of information per second

To put that in perspective, IBM states that high-def movies could be downloaded in one second at that speed, while the entire U. Library of Congress web archive could be downloaded in an hour. One of the unique features of parallel optic chips is the fact that they can simultaneously send and receive data. The Holey Optochip capitalizes on that feature, for its record-setting performance.

IBM shows off one terabit per second 'Holey Optochip'

IBM has outlined a prototype optical chipset called Holey Optochip that can transfer one terabit of information a second. IBM has unveiled a prototype optical chipset dubbed 'Holey Optochip' that can transfer data at one terabit a second. Image credit: IBM. That throughput — assuming the chip eventually scales — could provide a bandwidth boost that alters the supercomputing and datacentre landscape.

IBM creates 1Tbps Holey Optochip

Big Blue's new prototype chip surpasses major milestone, thanks to unlikely innovation: tiny holes in a quarter-inch chip, boosting data transfer. IBM said this evening that its scientists have developed a computer chip that can move a trillion bits of information a second. Known as the "Holey Optochip," the prototype optical chipset can transfer the equivalent of high-definition movies a second, or the entire U. Library of Congress Web archive in an hour, Big Blue said. The innovation is possible because IBM's scientists figured out that, by drilling 48 minuscule holes in a standard quarter-inch silicon CMOS chip, they were able to ramp up data transfer rates from what was possible. And by breaking through the terabyte-per-second barrier, the Holey Optochip is capable of data transfer at up to eight times the speed of today's parallel optical components, IBM said.

IBM unveils one trillion bit-per-second optical chip

IBM outlined a prototype optical chipset called Holey Optochip that can transfer one terabit of information a second. That throughputassuming the chip eventually scalescould provide a bandwidth boost that alters the supercomputing and data center landscape. These holes allow optical access through the back of the chip to 24 receiver and 24 transmitter channels. These lanes allow data to transfer freely.
