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 ...

Researchers have developed a new class of integrated photonic devices -- 'leaky-wave metasurfaces' -- that convert light initially confined in an optical waveguide to an arbitrary optical pattern in ...

These devices are the first to demonstrate simultaneous control of all four optical degrees of freedom, namely, amplitude, phase, polarization ellipticity, and polarization orientation--a world record ...

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 ...

Mode Division Multiplexing (MDM) technology stands as a cornerstone for enhancing transmission capacity in fiber-optic communication systems. However, in few-mode fibers, the group velocity ...

Nanophotonics and topology have gained significant interest due to the unique properties they offer. One area of focus is the investigation of topological edge states (TESs). These states have ...
