• Photonic mesh has unusually subtle effects

    Its effects are so small that only qualitative descriptions are applicable.

    An exotic photonic device whose characteristic effects are so tiny that only qualitative, rather than the more usual quantitative, descriptions are applicable has been created by scientists at three prominent American educational institutions, including the Massachusetts Institute of Technology (MIT), the Universities of California Davis and Los Angeles, and Cornell University.1 The specially made device was fabricated using a custom-designed molecular process.

    Two metal types

    Called a condensed photonic mesh, the device is formed from a combination of both base and noble metals; the effects of the catalytic fabrication technique newly invented by the researchers to assemble the mesh's tiny components render such a structure's usual electronic processes, such as semi- and superconductivity, moot.

    The mechanism behind the device's unusual characteristics is a structural instability known as evolved decomposition. Operating in regions near the core of the mesh, this method of decomposition ensures that natural processes are simultaneously accelerated and impededthe key to the reduction in scale of the mesh's interaction with the ambient environment.

    The researchers hope to commercialize the device after experimentally defining its properties in more detail.
