Twisted Edison: Filaments curling at the nanoscale produce light waves that twirl as they travel

Twisted Edison: Filaments curling at the nanoscale produce light waves that twirl as they travel



Researchers at the University of Michigan have shown that bright, bendable light can be produced with technology similar to the Edison light bulb. The discovery adds nuance to fundamental physics while providing a new opportunity for robotic vision systems and other applications for light that traces a helix in space.
