Shining a light around corners
Date:6/16/2010

We learned in science class that light beams travel in straight lines and spread through a process known as diffraction and they can't go around corners. But now researchers at Tel Aviv University are investigating new applications for their recent discovery that small beams of light can indeed be bent in a laboratory setting, diffracting much less than a "regular" beam.

These rays, called "Airy beams," were named 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. Now, the fortuitously-named Prof. Ady Arie and his graduate students Tal Ellenbogen, Noa Voloch-Bloch, Ayelet Ganany-Padowicz and Ido Dolev of Tel Aviv University's Faculty of Engineering have demonstrated new ways to generate and control Airy beams. Employing new algorithms and special nonlinear optical crystals, their research is reported in a recent issue of the scientific journal Nature Photonics.

Some of these new applications, such as a light source to generate beams that can turn around corners, or lighted spaces that contain no apparent light source, are still five or ten years away, says Prof. Arie. But his research has immediate applications as well. For example, because small particles are attracted to the highest intensities of a beam, the pharmaceutical and chemical industries can use the new beam to sort molecules according to size or quality, filtering impurities from drug formulations that might otherwise lead to toxicity and death.

A light that can twist around curves

Until now, reports an editorial review in the same issue of Nature Photonics, Airy beams have been generated through "linear diffraction" using tools that project a single color of light through glass plates of varying thicknesses. But using crystals they built in the lab, Tel Aviv University's approach uses another technique: nonlinear optics. Se
