U.S. scientists say they have built the world's first electrically powered Hybrid Silicon Laser using standard silicon manufacturing processes. The researchers from the University of California-Santa Barbara and Intel Corporation say the breakthrough addresses one of the last major barriers to producing low-cost, high-bandwidth silicon photonics devices for use inside and around future computers and data centers.

The researchers say they combined the light-emitting properties of Indium Phosphide with the light-routing capabilities of silicon into a single hybrid chip. When voltage is applied, light generated in the Indium Phosphide enters the silicon waveguide to create a continuous laser beam that can be used to drive other silicon photonic devices.

A laser based on silicon could drive wider use of photonics in computers because the cost can be greatly reduced by using high-volume silicon manufacturing techniques, the scientists said.

"This could bring low-cost, terabit-level optical 'data pipes' inside future computers and help make possible a new era of high-performance computing applications," said Mario Paniccia, director of Intel's Photonics Technology Lab.

Intel Says Breakthrough Could Lead To Powerful, Low-Cost Chips

San Francisco CA (AFP) Sep 18, 2006
Intel and university researchers announced Monday a breakthrough that could lead to a laser-producing chip that could vastly improve computing power at a low cost. Intel said the researchers for the company and the University of California at Santa Barbara developed a process that could allow the production of hybrid silicon-laser chips to use laser beams instead of wires to transfer data.
