Superlens with copper and copper oxide
David Ziemkiewicz, Karol Karpiński, Sylwia Zielińska - Raczyńska
We investigate the imaging properties of copper-based superlens surrounded by copper oxide (CuO). A subwavelength image resolution of the order is demonstrated theoretica…
Copper plasmonics with excitons
David Ziemkiewicz, Sylwia Zielińska-Raczyńska
We investigate the propagation of surface plasmons (SPPs) in a thin layer of copper surrounded by copper oxide CuO. It is shown that particularly strong excitons in CuO can…
Nonlinear optical properties and Kerr nonlinearity of Rydberg excitons in CuO quantum wells
David Ziemkiewicz, Gerard Czajkowski, Karol Karpiński +1
The quantum confiment of Rydberg excitons (REs) in quantum structures opens the way towards considering nonlinear interactions in such systems. We present a theoretical calculation…
Self-Kerr effect across the yellow Rydberg series
Corentin Morin, Jérôme Tignon, Juliette Mangeney +6
We investigate the nonlinear refraction induced by Rydberg excitons in . Using a high-precision interferometry imaging technique that spatially resolves the nonline…
