Suppression of the Chromatic Aberrations Using a Nanowire Metamaterial

Achromatic doublets have been used for decades to minimize the effects of chromatic aberrations inherent to single-glass optical lenses. Here, we propose a fundamentally different solution to correct the chromatic aberrations based on a nanowire metamaterial with low loss anomalous dispersion. We show that by coating a standard glass lens with the metamaterial it may be possible to design a compensated bi-layer lens with nearly no chromatic aberrations. The performance of the metamaterial based lens is compared with that of an achromatic doublet, showing that it may be an interesting alternative to the conventional solution.
