IBM Creation Could Boost Optical NetworkingResearchers say they've created the world's smallest solid-state light emitter, which could have applications in ultra-fast optical networks By InformationWeek May 1, 2003 (08:15)URL: http://www.informationweek.com/story/showArticle.jhtml?articleID=9400288 Researchers at IBM announced on Thursday that they have created the world's smallest solid-state light emitter, an advance that could have significant applications for optical networking. By configuring a carbon nanotube into a transistor, scientists are able to apply a negative charge to one end and a positive charge to the other. When the opposing charges meet, they neutralize each other and generate light. Because it's a transistor, the...
