Method Bends Beams of Light

Facebook X LinkedIn Email
TEL AVIV, Israel, June 18, 2010 — Contrary to what we learned in science class, that light beams travel in straight lines, researchers have discovered light can indeed be bent. The researchers from Tel Aviv University call these rays ‘Airy beams’ after English astronomer Sir George Biddell Airy, who studied the parabolic trajectories of light in rainbows, and were first created at the University of Central Florida. This is an artist's conception of simultaneous multiple nonlinear generations of Airy beams.

    nonlinear optics
    Nonlinear optics is a branch of optics that studies the optical phenomena that occur when intense light interacts with a material and induces nonlinear responses. In contrast to linear optics, where the response of a material is directly proportional to the intensity of the incident light, nonlinear optics involves optical effects that are not linearly dependent on the input light intensity. These nonlinear effects become significant at high light intensities, such as those produced by...
    wavelength
    Electromagnetic energy is transmitted in the form of a sinusoidal wave. The wavelength is the physical distance covered by one cycle of this wave; it is inversely proportional to frequency.
