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 ...

Combining photonics and electronics would bring the advantages of speedy optical data transfer to the increasingly miniaturized world of electronics. Ideally photonics and electronics elements would ...

'Random lasing' in disordered materials was first shown over 20 years ago, but the mechanism by which it occurs is much debated. High-resolution imaging correlated to the excitation of random lasing ...

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 ...

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 ...

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 ...

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 ...

This study is led by professor Tianrui Zhai (Faculty of Science, Beijing University of Technology). The fiber braiding cavity is designed to achieve the red-green-blue (RGB) whispering gallery mode ...

The FBI has launched a 90-day nationwide campaign offering rewards of up to $10,000 for information leading to the arrest of people who point lasers at aircraft. The FBI and the Federal Aviation ...

(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 ...
