An international team of researchers led by Kyushu University and Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, has demonstrated stable, continuous lasing at room temperature ...
Exceptional points (EPs) are non-Hermitian singularities where two or more eigenstates coalesce, resulting in the eigenspace collapsing in dimensionality. Over the past decade, researchers have ...
Lasing at the nanometre scale promises strong light-matter interactions and ultrafast operation. Plasmonic resonances supported by metallic nanoparticles have extremely small mode volumes and high ...
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 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 ...
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 ...
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 ...
