( Vienna University of Technology ) Light waves can oscillate in different directions. Special materials can rotate the polarization of light -- but usually, this effect is very small. Scientists at the Vienna University of Technology have now managed to build a device that arbitrarily rotates a beam of light by tuning the electric potential applied to a thin layer of material. This produced an ...
