The optoelectronic properties of topological insulators have many attractions, including a robustness to defects, imperfections and sharp corners. This robustness inspired a group of scientists to ...

When a water droplet interacts with a surface to form a contact angle, the interfacial molecular forces determine the geometry of a droplet resonator. Dramatic mechanical changes at the interface play ...

A directional random laser mediated by transverse Anderson localization in a disordered glass optical fiber is reported. Previous demonstrations of random lasers have found limited applications ...

Miniaturized lasers capable of emitting over the full visible spectrum have been demonstrated to be an essential tool for versatile photonic devices ranging from sensors to full-color laser display ...

Crystalline lithium niobate (LN) is considered the “silicon of photonics” because of its outstanding optical properties, including a broad transparency window and high piezoelectric, acousto-optic, ...

Since lasers were first developed, the demand for more adaptable lasers has only increased. Chiral nematic liquid crystals (CLCs) are an emerging class of lasing devices that are poised to shape how ...

An electrically pumped photonic-crystal laser with improved tuning sensitivity could be used for free-space communications. Researchers at the California Institute of Technology have made the first ...

(Nanowerk News) Tiny molecular forces at the surface of water droplets can play a big role in laser output emissions. As the most fundamental matrix of life, water drives numerous essential biological ...
