A Möbius Strip Made of Light

A Möbius Strip Made of Light

Most nerdy kids, of the type that would grow up to read IEEE Spectrum , were excited when they first learned about the Möbius strip , a three-dimensional shape with only one surface. Many immediately fashioned their own, by cutting a thin strip of paper, twisting it, and joining one end to the other to make a continuous surface. Now scientists have figured out how to make a Möbius strip out of light. The researchers, from Canada, Europe, and the United States, were able to twist the polarization of a light beam in order to form a 3-D structure out of an electric field that had the same topology as a Möbius strip made of matter would. Lightwaves consist of both an electric and a magnetic field, which oscillate perpendicular to each other. Polarization refers to the direction in which the electric field oscillates. Under normal circumstances the polarization does not change ...
