    Scientists Shape Light to Travel Along a Single Branch

    Article obtained from Photonics RSS Feed.

    Scientists at the Vienna University of Technology (TU Wien) showed how the branched flow of light can be made to propagate along a single branch rather than along many branches at the same time. Their approach, which they think could be applied to different types of waves, from scalar to vector and from two to three dimensions, is based on shaping the incoming wavefront. The wave signal is then sent exclusively along a single preselected branch and is hardly noticeable anywhere else.

    The branched flow of lightwaves occurs when an incoming wave splits into several paths, reaching some places with high intensity, while avoiding others almost completely. To control the branching, the researchers first allowed the wave to branch out in…
