In a recent breakthrough, researchers have developed advanced optically-active metasurfaces that are capable of achieving dynamic dual-mode modulation. This new technology could lead to a range of applications, such as optical communications, imaging, and sensing.

The optically-active metasurfaces were developed by a team of researchers from Northwestern Polytechnical University in China. The team used a combination of nanostructured materials and optical effects to create a metasurface that can dynamically switch between two different optical modulation modes. In one mode, the metasurface can be used to manipulate the polarization and phase of light, while in the other mode, it can be used to modulate light intensity. This is the first time that such a dual-mode modulation has been achieved.

The researchers believe that this new technology could have a wide range of applications, such as in optical communication systems, imaging systems, and sensors. It could also provide a way to create high-speed, low-cost optical devices.
