"selectively amplify or dampen specific parts of beam microscopic level counteract onset of degradation... stay in picture of nebula, light-scattering properties completely suppressed... modifying material... possible transmission of specific light signal... successfully tackled this challenge. In their experiments, they were able to recreate and observe the microscopic interactions of light signals with their newly developed active materials in networks of kilometer-long optical fibers"
