Nanoscale Bow Ties Act as Optical Antennas

Hank Hogan

Researchers at Stanford University in California have used bow-tie-shaped optically resonant metallic structures to create resist features smaller than 30 nm using an 800-nm laser beam in a two-photon absorption process. The technique could have applications in semiconductor manufacturing as a means of creating very small features using relatively long wavelength sources. An atomic force microscopy image reveals the resist covering a bow-tie antenna that was exposed to the 27-μW output of an 800-nm laser (upper left). The gap in the bow tie is 36 nm and is clearly visible in the...Read full article

    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
