【 摘 要 】

Cavity-exciton polaritons have attracted much interest because these light-matter quasiparticles are very promising for various optoelectronic applications. Bragg-polaritons have been discussed as new tools for tailoring light-matter interactions. These structures can be created by incorporating quantum wells (QWs) periodically into a distributed Bragg reflector (DBR). The advantage of this sample type is the high number of QWs which can be embedded into the sample in order to increase the Rabi-splitting energy. Calculations show, that the coverage of the sample with a thin metal layer results in an increase of the temperature stability of the strong coupling regime. In addition, this concept enables a specific spectral variation of the cavity resonance allowing for the manipulation of the light-matter interaction.
