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 ...

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 ...

Real-space (left) and Fourier space (right) photoluminescence image of a hexagonal boron nitride waveguide. The real-space image shows where photoluminescence is emitted from within the sample, while ...

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 ...

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