This image is part of the series linked in the previous post on the laser turning 50, but it deserves highlighting as a very cool nanotechnology image.
Researchers at the University of California, Berkeley, have created the smallest semiconducting laser, which could eventually be used for optical computing. A cadmium sulfide wire 50 nanometers in diameter generates visible light and holds it in a five-nanometer space.
