Metasurfaces control polarized light at will

Researchers have uncovered hidden potential in metasurfaces and demonstrated optical devices that manipulate light's polarization state with an unprecedented degree of control. The research demonstrates a new way to control polarized light with metasurfaces. This new approach -- in which the researchers can engineer a holographic image with a polarization-tunable response across the image itself -- could lead to applications in diverse fields including imaging, microscopes, displays, and even astronomy.
