Intel Labs has announced construction of an eight-wavelength, distributed feedback (DFB) laser array on a chip for optical laser communications modules in datacenters.

company headquarters September 18, 2006 in Santa Clara, California. Intel announced today that its researchers, teamed up with researchers from the University of California, Santa Barbara, have successfully used standard silicon manufacturing processes to build the world?s first electrically powered Hybrid Silicon Laser, a key element in producing low-cost, high-bandwidth silicon photonics devices for use inside and around future computers and data centers.
A WDM laser array generates multiple beams of light at different frequencies that can be combined onto one fiber, thus pushing more bandwidth through the optical fiber than achieved by a single-frequency laser. In the recent announcement from Intel, the experimental eight-laser DFB array generates eight beams of infrared light with uniform 200GHz channel spacing.
First, optical gratings etched into silicon sit adjacent to each InP light emitter, tuning the light from each emitter. The physical pitch of each of the eight gratings causes each laser to generate a precise beam of light at a different frequency. These gratings are made on Intel’s standard 300mm CMOS wafer line using deep-UV immersion lithography, which is a high-volume, low-cost process.
immersion lithography, a high-volume, low-cost process. Light pipes, modulators, combiners, and detectors are also etched into the silicon using the same CMOS process technology.The ability to manufacture the most critical photonic components as a hybrid, monolithic chip will allow Intel to greatly improve the bandwidth of its optical modules while reducing their costs relative to today’s modules.
