Uber-nano nanolasers could lead to faster computers, reliable internet, neverending list of awesome things
Researchers at Arizona State University and Technical University of Eindhoven in the Netherlands have been collaborating on a project to make lasers significantly smaller than the ones that are currently available, by finding a way around the traditionally accepted diffraction limit — the idea that the size of lasers in any one dimension (say, thickness) is limited to half of the wavelength involved. One way around the size limitation, they’ve found, is to use a combination of semiconductors and metals like gold and silver, which causes electron excitement which helps confine the light in a laser to smaller spaces than that of the supposed limit. Using this method, the team has created nanoscale lasers that are one quarter of the wavelength or smaller — as opposed to the previously accepted size limitation of one half of the wavelength.
