Four-Wave Mixing Paves Way for Optical Computing

Facebook X LinkedIn Email
LONDON, Dec. 4, 2017 — Researchers have reduced the distance over which light can interact by 10,000 fold. Their work could advance optical computing by bringing optical processing into the range of electrical transistors, which are currently used to power personal computers. These are nanofocusing and optical mode properties of the organic hybrid gap plasmon waveguide on the silicon platform used for degenerate four-wave mixing. The insets depict the scaled electromagnetic mode distributions for a wide metal gap of 500 nm and a narrow metal gap of 25 nm, along with the chemical formula for MEH-PPV.

    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...
    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.
