The project targets the efficient manipulation of light beams with simultaneous frequency conversion at an ultrathin metal-zinc oxide metasurface. We plan to manipulate the amplitude and phase of the nonlinear waves based on the structural design and material composition on a nanoscale by utilizing a nonlinear Pancharatnam-Berry phase. By coupling the plasmonic resonances of the metal nanostructures to the virtual and real transitions in zinc oxide, we will enhance the nonlinearity of the combined system. With this concept, we will realize ultrathin nonlinear optical components, like nonlinear lenses and beamsplitters.

该项目的目标是在超薄金属-氧化锌超表面上高效操纵光束并同时进行频率转换。我们计划通过利用非线性Pancharatnam-Berry相位，基于纳米尺度上的结构设计和材料组成来操纵非线性波的振幅和相位。通过将金属纳米结构的等离子体共振耦合到氧化锌中的虚跃迁和真实的跃迁，我们将增强组合系统的非线性。有了这个概念，我们将实现非线性光学元件，如非线性透镜和分束器。
