Photonic crystals—repeatable structures with periods comparable ... "Liquid crystal molecules have the shape of an ellipsoid elongated in one direction. This characteristic feature leads to the ...

Photonic-crystal surface-emitting laser (PCSEL) is a promising technology that can completely revolutionize what lasers ...

In a first for the field, researchers from The Grainger College of Engineering at the University of Illinois Urbana-Champaign ...

As one of examples, Figure 2(a) shows how to create a photonic topological insulator employing a honeycomb-lattice photonic crystal. When six triangular holes are shifted inwards, it becomes a ...

Ancient Roman “wow glass” has photonic crystal patina forged over centuries Precise hierarchical molecular self-assembly formed so-called "Bragg stack" reflectors.

Dec 08, 2024: Space-time crystals, an important step toward new optical materials (Nanowerk News) Photonic time crystals consist of materials with uniform composition in space but properties that vary ...

Magnonic crystals are artificial periodic structures designed to control and manipulate the propagation of spin waves, also known as magnons. These crystals are the magnetic analogs of photonic ...
