Trapped light orbits within an intriguing material

16 julio 2015

Hexagonal boron nitride bends electromagnetic energy in unusual and potentially useful ways. Physicists recently found that nanoscale granules of the material can store light. Now they have shown that the trapped light, polariton rays, propagate along paths at fixed angles with respect to the atomic structure of the material and at certain ‘magic’ frequencies form simple closed orbits. The insight could guide the development of applications such as nanoresonators, hyperlenses or infrared photon sources.img src=»» height=»1″ width=»1″ alt=»»/
