Silicon Chips May Go 'Green'

Facebook X LinkedIn Email
SAN JOSE, Calif., Oct. 16, 2009 -- Harvesting optical energy currently lost through heat dissipation in optoelectronic devices could allow them to actually generate more power than they use and help make silicon chips and compound semiconductors more "green." In a well-attended presentation Wednesday afternoon at Frontiers in Optics 2009, Sasan Fathpour, assistant professor of integrated photonics & energy solutions at the University of Central Florida's CREOL (College of Optics and Photonics), outlined the benefits and challenges facing engineers attempting to make integrated photonic components more environmentally...Read full article

    optoelectronic
    Pertaining to a device that responds to optical power, emits or modifies optical radiation, or utilizes optical radiation for its internal operation. Any device that functions as an electrical-to-optical or optical-to-electrical transducer. Electro-optic often is used erroneously as a synonym.
    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...
    power
    With respect to a lens, the reciprocal of its focal length. The term power, as applied to a telescope or microscope, often is used as an abbreviation for magnifying power.
