Abstract:
Nanoscale optical elements offer the potential of entirely new modalities of superresolution imaging, superfocussing and slow light utilizing the unique properties of negative metamaterials. We discuss our recent work on the experimental demonstration of superresolution imaging using anisotropic nanowire metamaterials. We have also developed new concepts to control the speed of light using metamaterial cladded optical waveguides. These nanoscale metamaterial waveguides offer the prospect of on-chip slow light devices where light speeds are reduced by orders of magnitude, enabling ultra-compact optical delay lines and buffers. The results of this work have potential applications in metamaterials imaging components and optoelectronic systems for military and civilian telecommunication systems.
