It was recently discovered that transparent micro-spheres and cylinders can function as super-resolution lens (i.e superlens) to focus light beyond the diffraction limit. A number of high-resolution applications based on these lenses have been successfully demonstrated and span nanoscopy, imaging and spectroscopy. Fabrication of these superlenses, however, are often complex and require sophisticated engineering processes. Clearly an easier model candidate, such as a naturally occurring superl...
