New, ultrathin optical devices shape light in exotic ways

3 septiembre 2015

Researchers have developed innovative flat, optical lenses that are capable of manipulating light in ways that are difficult or impossible to achieve with conventional optical devices. The new lenses are not made of glass. Instead, silicon nanopillars are precisely arranged into a honeycomb pattern to create a «metasurface» that can control the paths and properties of passing light waves.
