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…
Electro-optical properties of excitons in CuO quantum wells: II continuum states
David Ziemkiewicz, Gerard Czajkowski, Karol Karpiński +1
We present theoretically calculated optical functions for CuO quantum well (QW) with Rydberg excitons in an external, homogeneous electric field parallel to the QW planes for t…
Controlled processing of signal stored in metamaterial with tripod structure
S. Zielińska-Raczyńska, D. Ziemkiewicz
In the present paper we have discussed in detail electromagnetically induced transparency and signal storing in the case of one signal pulses propagating in a classical electric me…
Pulse propagation in a medium optically dressed by a phase-modulated field
Andrzej Raczynski, Jaroslaw Zaremba, Sylwia Zielinska-Raczynska
Pulse propagation is studied in an EIT medium with the control field having a periodically varying phase (chirp). Based both on numerical calculations and on an approximate approac…
Excitonic Spectra of Wide Parabolic Quantum Wells
Gerard Czajkowski, Sylwia Zielińska-Raczyńska, David Ziemkiewicz
The optical properties of wide Quantum Wells are considered, taking into account the screened electron-hole interaction potential and parabolic confinement potentials, different fo…
