Transmission enhancement in three-dimensional rolled-up plasmonic metamaterials containing optically active quantum wells

TL;DR

This paper demonstrates that three-dimensional rolled-up plasmonic metamaterials with quantum wells can significantly enhance light transmission by tuning surface plasmon polariton resonances and exploiting Fabry-Perot effects.

Contribution

It introduces a novel design of 3D rolled-up metamaterials with quantum wells that achieve enhanced optical transmission through resonance matching.

Findings

Strong transmission enhancement observed with p-polarized light

Resonance matching amplifies the effect

Fabry-Perot resonances further increase transmission

Abstract

We investigate three-dimensional rolled-up metamaterials containing optically active quantum wells and metal gratings supporting surface plasmon polarition resonances. Finite-difference time-domain simulations show that by matching the surface plasmon polarition resonance with the active wavelength regime of the quantum well a strong transmission enhancement is observed when illuminating the sample with p-polarized radiation. This transmission enhancement is further increased by taking advantage of the Fabry-Perot resonances of the structure.
