Harvard creates a material that lets light go 'infinitely fast'
Researchers at Harvard University announced recently that they had successfully developed a means of manipulating light at the nanoscale, which could lead to photonic-based (rather than electronic) telecommunications. Think, ubiquitous fiber optics. The team reportedly developed an on-chip metamaterial made from silicon pillars embedded in polymer and wrapped in gold film that exhibits a refractive index of zero. In English, that means that the phase of light passing through this material can travel infinitely fast without violating the known laws of physics.
