Spiral Microlasers Theorized

WASHINGTON, Jan. 26, 2009 – Theoretically, disk-shaped lasers as small as a speck of dust could one day beam information through optical computers. Typically, a perfect disk will spray light out, not as a beam, but rather in all directions. According to the Optical Society of America, adding a single notch to the disk edge provides a single outlet for laser light to stream out.  To increase the speed of computers and telecommunications networks, researchers are looking to replace electrical currents with beams of light that would originate from small semiconductor lasers. However, shrinking lasers down to a few...Read full article

    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
