Caltech research investigates metasurface optics for bending light

Researchers at Caltech are experimenting with metasurface optics to bend and focus light in a finely controllable way by using carefully designed microscopic structures on an otherwise flat surface.

In a paper published by Nature Communications on October 10, the researchers describe a technology called "folded metasurface optics," which is a way of printing multiple types of metasurfaces onto either side of a substrate, like glass.
