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 ...

'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 ...

Topological photonics have provided new insights for the manipulation of light. Analogous to electrons in topological insulators, photons travelling through the surface of a topological photonic ...

Bose–Einstein condensation of polaritons in periodically modulated cavities is a very interesting fundamental effect of the physics of many-body systems. It is also promising for application in ...

Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...

Water droplet contact angle dramatically increases lasing emissions, from Qiao et al., doi 10.1117/1.AP.3.1.016003. Credit: Qiao et al. Lasing mechanism at the surface of water droplets can be used to ...

Abstract: Plasmonics, a technique to tightly concentrate light down to the nanoscaleby coupling photons to surface plasmons,has been employed to downscalelasersto sub-wavelength dimensions. The ...

We investigate the temperature dependence of the lasing characteristics (lasing peak energy spontaneous emission factor β, and lasing threshold) of an irregular-shaped-ZnO-microparticle laser. The ...

The innovative advances in ultrafast laser technologies provide new strategies for remote sensing of atmospheric pollutants and hazardous biochemical agents. The high-energy femtosecond laser can ...
