Rydberg exciton-polaritons in a magnetic field

E Laird, FM Marchetti, DK Efimkin, MM Parish… - Physical Review B, 2022 - APS
We theoretically investigate exciton-polaritons in a two-dimensional (2D) semiconductor
heterostructure, where a static magnetic field is applied perpendicular to the plane. To …

Optical-to-microwave frequency conversion with Rydberg excitons

D Ziemkiewicz, S Zielińska-Raczyńska - Physical Review B, 2023 - APS
A copper-based plasmonic system is presented to provide optical-to-microwave photon
conversion. The process uses highly excited levels in Cu 2 O Rydberg excitons and takes …

Nonlinear optical properties and Kerr nonlinearity of Rydberg excitons in quantum wells

D Ziemkiewicz, G Czajkowski, K Karpiński… - Physical Review B, 2022 - APS
The quantum confinement of Rydberg excitons (REs) in quantum structures opens the way
towards considering nonlinear interactions in such systems. We present a theoretical …

Copper plasmonics with excitons

D Ziemkiewicz, S Zielińska-Raczyńska - Physical Review B, 2022 - APS
We investigate the propagation of surface plasmons in a thin layer of copper surrounded by
copper oxide Cu 2 O. It is shown that particularly strong excitons in Cu 2 O can have a …

Second-harmonic generation of blue series excitons and magnetoexcitons in

A Farenbruch, D Fröhlich, H Stolz, DR Yakovlev… - Physical Review B, 2021 - APS
Nonlinear optical studies of the yellow and green exciton series in Cu 2 O have been
reported for more than 40 years. Because of the band structure (the two highest even-parity …

Electro-optical properties of excitons in quantum wells. I. Discrete states

D Ziemkiewicz, G Czajkowski, K Karpiński… - Physical Review B, 2021 - APS
We present a theoretical calculation of optical functions for Cu 2 O quantum well (QW) with
Rydberg excitons, in an external homogeneous electric field of an arbitrary strength. Two …

Excitation of weak and strong guided waves in a semiconductor slab and their strong coupling with confined magnetoexcitons

PL Valdés-Negrin, NM Makarov, F Pérez-Rodríguez - Physical Review B, 2022 - APS
We have obtained and analyzed optical spectra of a semiconductor slab, containing a
quantum well which serves as a source of magnetoexcitons in the presence of an external …
