The chipmaker Intel aims to revolutionize our ways of communication
by using a new technology to create very high performing optical devices.
The
new technology is called Silicon Photonics and it uses standard silicon to send
and receive optical information among computers and other electronic devices.
Intel researchers have made a new breakthrough in this filed
by achieving world-record performance
using a silicon-based Avalanche Photodetector (APD). The silicon-based APD is a
light sensor that achieves superior sensitivity by detecting light and
amplifying weak signals as light is directed onto silicon.
This APD device used silicon and CMOS processing to achieve a “gain-bandwidth
product” of 340 GHz - the best result ever measured for this key APD
performance metric.
Thanks to this technology, Intel could have a viable solution
for future bandwidth needs of data-intensive computing applications such as
remote medicine and lifelike 3-D virtual worlds.
Also, silicon photonics will provide substantial size, cost, and
power savings over traditional optical communication solutions.
This advance builds upon previous Intel breakthroughs such
as fast silicon modulators and hybrid silicon lasers.
This new achievement opens the door to lower the cost of
optical links running at data rates of 40Gbps or higher and proves, for the
first time, that a silicon photonics device can exceed the performance of a
device made with traditional materials.
