Abstract

Laser communications hold the potential to bring internet-like speeds (exceeding Gb/s) to data transmission in space. One of the major challenges of the laser communications is the necessity to accurately direct narrow beams. In the present talk, we discuss how electrically reconfigurable active metasurfaces can address this challenge. We perform an optical link budget analysis and discuss how the link range can be extended by increasing the aperture diameter or the input optical power. To assess maximal available output powers from realistic metasurface-based apertures, we experimentally probe the gate-tunable performance of indium tin oxide (ITO)-based active metasurfaces upon high-power illumination.
