Study: Giant ultrafast dichroism and birefringence with active nonlocal metasurfaces

The fine and efficient control of the properties of light at ultrafast speed down to the picosecond timescale is a challenging task, crucial for many scientific applications and technologies. For instance, in free-space optical links, manipulating on demand the attributes of light can be exploited to encode and transfer digital information robustly, over long distances and without optical fibers.
