When light strongly interacts with matter, it can produce unique quasi-particles called polaritons, which are half light and half matter. In recent decades, physicists explored the realization of polaritons in optical cavities ...
Today, electronic and photonic devices are ubiquitous in smart phones, computers, light sources, sensors, and communications. To underpin the demand for optoelectronic applications, functional materials are essential. For ...
Inspired by the mechanism behind light-sensitive sunglasses, a team led by a North Carolina State University researcher invented a family of fluorescent dyes to illuminate biological processes at a very small scale—comparable ...
