It represents an important aspect for possible future innovations and technological development. This opens the door for fields such as hyper-lenses that create more powerful sensors and microscopes branching off from nano-photonic technology. Based on clouds of electrons called "surface plasmons", tiny spasers are created.
A detailed paper describing this research is posted online in the journal Nature, reporting on work done by researchers at Purdue Norfolk State University and Cornell University.
