Caltech’s nanoscale device can reflect and direct light in desired ways

, , , , , , , , , , Edit
An incident laser beam (green) hits Caltech's new space-time metasurface and gets modulated by tunable, nanostructured antennas, creating steerable beams of light at different frequencies (blue) that could be used as optical channels for transmitting data on Earth or in space.

The innovation is pointing the way to future wireless communication channels.
