(Nanowerk News) Dielectric optical microresonators confine and concentrate light in a tiny circular path due to multiple near total internal reflections at the curved dielectric-air interface, where ...

Lead-halide perovskites are considered one of the most promising materials for the production of the lasers of the future. A new joint Tel Aviv University (TAU) and Karlsruhe Institute of Technology ...

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 ...

Suppression of long-lived energetic states called triplet excitons shown to be key for preventing the "lasing death" that has been limiting long operation An international team of researchers led by ...

The team's experimental setup: Atoms are cooled and slowed inside a vacuum chamber, until they can be trapped in a lattice inside a cavity (black triangular cavity spacer in the bottom half of the ...

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 Los Alamos National Laboratory team has overcome key challenges toward technologically viable high-intensity light emitters based on colloidal quantum dot technology, resulting in dual-function ...

A layer of perovskite is shown lasing green under continuous operation at room temperature. Credit: Chuanjiang Qin, Changchun Institute of Applied Chemistry, Chinese Academy of Sciences On paper, ...

New research shows that lasing for over one hour at room temperature can be achieved from low-cost quasi-2D perovskite materials by properly managing losses caused by triplet excitons. This new ...

(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 ...
