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 ...

Lithium niobite (LN) with an ultra-wide optical transparent window has shown excellent nonlinear, electro-optic, acoustic-optic, piezoelectric, thermoelectric and photorefractive effects. It is an ...

image: New spectroscopic technique for studying nanostructures demonstrates that stibnite nanodots can act as high-optical-quality waveguides and are promising candidates as photoswitchable materials ...

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 ...

Interferometers, devices that can modulate aspects of light, play the important role of modulating and switching light signals in fiber-optic communications networks and are frequently used for gas ...

Photonic computing represents not a radical departure from familiar territory, but rather a natural extension along the electromagnetic spectrum. The transition from gigahertz to hundreds of terahertz ...

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 ...
