Interaction between Metamaterial Resonators and Inter-subband transitions in Semiconductor Quantum Wells
arXiv:1105.3523 · doi:10.1063/1.3592266
Abstract
We report on the coupling and interaction between the fundamental resonances of planar metamaterials (split ring resonators) and inter-subband transitions in GaAs/AlGaAs quantum wells structures in the mid-infrared. An incident field polarized parallel to the sample surface is converted by the metamaterial resonators into a field with a finite component polarized normal to the surface, and interacts strongly with the large dipole moment associated with quantum well inter-subband transitions.
