论文摘要
我们研究了被铜氧化铜包围的基于铜的超级的成像特性（Cu $ _2 $ O）。理论上证明了$λ/9 $的次级映像分辨率，并在数值模拟中进行了验证。结果表明，cu $ _2 $ o中激子的存在影响镜头的静态和动力学特性。特别是，研究了由激子共振光谱区域吸收引起的图像质量的改善。系统中的等离子体 - 脱离相互作用可能会为可调的高度非线性超级设计铺平道路。
We investigate the imaging properties of copper-based superlens surrounded by copper oxide (Cu$_2$O). A subwavelength image resolution of the order $λ/9$ is demonstrated theoretically and verified in numerical simulations. It is shown that the existence of excitons in Cu$_2$O influence the static and dynamical optical properties of the lens. In particular, an improvement of image quality caused by absorption in the spectral region of excitonic resonances is investigated. The plasmon-exciton interaction in the system may pave the way to a tunable, highly nonlinear superlens designs.
