Researchers have designed a metasurface that can be continuously tuned from linear to elliptical birefringence, opening up the entire space of polarization control with just one device. This single metasurface can operate as many birefringent materials in parallel, enabling more compact polarization manipulation, which could have far-reaching applications in polarization imaging, quantum optics, and other areas.
