Researchers at the University of California, Berkley, have developed a way to "grow" nanolasers on a piece of silicon which is believes to pave the way for new generation of laser processors.

In fact the silicon is bad at generating light. Scientists had previously tried to develop chips made of silicon and so-called "III-V" (three-five) semiconductor materials, but this approach has problems of its own.

Lead researcher and UC Berkeley grad student Roger Chen said in a press release: "Growing III-V semiconductor films on silicon is like forcing two incongruent puzzle pieces together. It can be done, but the material gets damaged in the process."But, the researchers developed nanotechnology structures called "nanopillars" made of indium gallium arsenide on the silicon. These nanopillars were capable of producing near-infrared laser light at room temperature.

The researchers' report will be published in the journal Nature Photonics.

Processors are only one use for this technology; researchers also say it could be used in biochemical sensors.
please i want more information about thz topic till evening urgently to submit ppt.....
