Superprism phenomenon in photonic crystals: Guiding the path of light
Photonic crystals can be thought of as 'optical analogues' to electronic semiconductors, and have been widely studied for their periodically-varying indexes of refraction. This allows for controlling the propagation of ...
Fabrication of optically active nanostructures by chemical methods
A new method of fabricating long-range, planar arrays of discrete, submicron metal structures on glass or SiO2/Si surfaces has been developed without the use of resist masks or chemical etching. The approach combines ...
Reshaping the metallic surface of a gold nanoshell
Two methods for the controlled reshaping of metal nanoparticles have been investigated: pulsed laser induced reshaping and surfactant-mediated restructuring. The laser induced shape changes of gold nanoshells have been ...
