Researchers have created a brand-new category of integrated photonic devices called “leaky-wave metasurfaces” that can transform the light that was once constrained in an optical waveguide into any optical pattern in free space. These devices’ simultaneous control of all four optical degrees of freedom—amplitude, phase, polarization ellipticity, and polarization orientation—is a global first. The devices [..]
