Waveguides are structures designed to direct and control the propagation of electromagnetic waves from one point to another. They play a crucial role in various fields, including telecommunications, ...

Researchers at Columbia Engineering have developed a new class of integrated photonic devices—"leaky-wave metasurfaces"—that can convert light initially confined in an optical waveguide to an ...

(Nanowerk Spotlight) The concepts of metamaterials and metasurfaces have spawned massive novel applications in free-space optics. However, recent research also indicates that they possess prominent ...

Comprised of judiciously engineered microscopic photonic structures with subwavelength features, the concept of metasurface and metamaterials have proven fruitful results in the realm of meta-optics.

Scientists announce the discovery of slab waveguides based on the two-dimensional material hexagonal boron nitride. The U.S. Naval Research Laboratory (NRL), in collaboration with Kansas State ...

Researchers have now achieved high-Q photonic flatbands that span the entire k-space of nonlocal metasurfaces and can be selectively tailored for linearly polarized or circularly polarized light, ...
