  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.
