Molecular Scale Imaging with a Smooth Superlens
Pratik Chaturvedi, Wei Wu, VJ Logeeswaran +5
We demonstrate a smooth and low loss silver (Ag) optical superlens capable of resolving features at 1/12th of the illumination wavelength with high fidelity. This is made possible…
Nonlinear Optical Spectroscopy of Photonic Metamaterials
Evgenia Kim, Feng Wang, Wei Wu +2
We have obtained spectra of second-harmonic generation, third harmonic generation, and four-wave mixing from a fishnet metamaterial around its magnetic resonance. The resonant beha…
Modulation of Negative Index Metamaterials in the Near-IR Range
Evgenia Kim, Wei Wu, Ekaterina Ponizovskaya +5
Optical modulation of the effective refractive properties of a "fishnet" metamaterial with a Ag/Si/Ag heterostructure is demonstrated in the near-IR range and the associated fast d…
Overlay Alignment Using Two Photonic Crystals
Can Peng, Keith Morton, Zhaoning Yu +1
In this paper we proposed a novel overlay alignment method using two sets of identical photonic crystals (PhCs). In this method the reflection or transmission spectrum of the two o…
