Epsilon-near-zero strong coupling in metamaterial-semiconductor hybrid structures

Nano Lett. 2013;13(11):5391-6. doi: 10.1021/nl402939t. Epub 2013 Oct 18.

Abstract

We present a new type of electrically tunable strong coupling between planar metamaterials and epsilon-near-zero modes that exist in a doped semiconductor nanolayer. The use of doped semiconductors makes this strong coupling tunable over a wide range of wavelengths through the use of different doping densities. We also modulate this coupling by depleting the doped semiconductor layer electrically. Our hybrid approach incorporates strong optical interactions into a highly tunable, integrated device platform.
