In this contribution we study the fundamental interactions of a metamaterial system built of dipole elements in the THz regime. We investigate the coupling between the elements for different geometries, as well as symmetric and asymmetric structures and analyze the response of the system with changing refractive index of the surrounding medium. Finally, we use these structures to access intersubband...
In this contribution, effective coupling between intersubband optical transitions and planar metallic resonators is presented. We discuss and demonstrate features unique to such a system and point out the consequences for active terahertz metamaterial devices.
The interaction of metamaterials and terahertz intersubband transitions is investigated in the strong coupling regime. We demonstrate that the resonant frequency of the metamaterial can be tuned by etching without destroying the strong interaction.
