Abstract: An active metasurface that provides low-loss and high-bandwidth modulation control of light includes a number of cells arranged on a substrate. A controller dynamically alters a voltage differential supplied to the electrodes of each of the cells is adapted to alter refractive index of each of the high-index dielectric blocks in order to controllably steer light exiting the cell.

Abstract: A device includes a controller with a processor and memory with instructions for controlling power to a light source such that the light source emits a frequency-modulated continuous light beam that, over time, includes an up region, a down region, and a flat region. The up region includes increasing a frequency of the continuous light beam, the down region includes decreasing the frequency of the continuous light beam, and the flat region includes maintaining the frequency of the continuous light beam at a constant frequency.
