Optical properties of Rydberg excitons in CuO based superlattices
David Ziemkiewicz, Gerard Czajkowski, Sylwia Zielińska-Raczyńska
Combining the microscopic calculation of superlattice minibands and the macroscopic real density matrix approach one can obtain electric susceptibilities of the superlattice system…

Optical to microwave frequency conversion with Rydberg excitons
David Ziemkiewicz, Sylwia Zielińska-Raczyńska
A novel, copper-based plasmonic system is presented to provide optical to microwave photon conversion. The process uses highly excited levels in Cu2O Rydberg excitons and takes adv…
