Researchers fabricated 20mm length waveguides made of the superconducting metal niobium (right). It shows improved conductivity compared with normal metal materials such as a gold-plated tellurium ...

The first theoretical models of the propagation of an electromagnetic field in a waveguide date back to the second half of the 19th century (Hertz, Debye, Rayleigh). The technological fallout for long ...

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.

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, ...

What are modal effects? Integrated photonics—the devices and the materials used to make them happen. One of the key planar-waveguide configurations: the ring resonator. The roots of waveguide optics ...
