Light can usually be confined only with mirrors, or with specialized materials such as photonic crystals. Both of these approaches block light beams; last years finding demonstrated a new method in which the waves cancel out their own radiation fields. The new work shows that this light-trapping process, which involves twisting the polarization direction of the light, is based on a kind of vortex—the same phenomenon behind everything from tornadoes to water swirling down a drain.
