Intel Discovers Silicon Photonics For Transmitting Data Using Light

Intel researchers have discovered an important breakthrough in silicon photonics. Intel is working on a new avalanche photodetector which can detect and amplify light signals. This discovery is the next step in developing ways to transmit data through light.

Intel Corp is working on new ways to transmit data by using light signals. The new discovery an important breakthrough in silicon photonics.
The business technology company is currently working on a new breakthrough which can detect and amplify light signals through avalanche photodetectors, or ADP. Intel says that the discovery is the next step in developing ways to transmit data through light.
"With APDs, we have an opportunity to develop very high-speed optical links with the ability to drive faster and lower-cost technology in and around the platform," Mario Paniccia, an Intel Fellow and director of the company's Photonics Technology Laboratory, said in a statement.
The purpose of photonics is to replace more conventional electrical interconnects that use copper wiring with on-chip components that use light to transmit data. This type of technology offers greater bandwidth and amplification abilities. Intel researchers are searching ways to build these types of photodetectors for less money.
Intel wants to see the technology developed first for desktop PCs. It wants to create an affordable solution first before deploying it in data centers for mainstream use.
What makes the avalanche photodetector different from other photodetectors is the sensor. For instance, the avalanche photodetector is a sensor that both detects light pulses and amplifies them as light is directed into the silicon. The APD, or avalanche photodetector, can absorb and then amplify the light pulse and produce tens or hundreds of electrical signals.
Intel CTO Justin Rattner said he expects silicon photonics to enter the market as early as 2010.
