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…

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…
