We demonstrate experimentally a subdiffraction light pattern, with a period down to 150 nm, at the surface of an optimized silicon nanostructured thin film. We show, using near-field and far-field characterization, that this subdiffraction pattern can be translated and rotated just by changing the illumination angle. The movable high frequency light pattern paves the way for subdiffraction resolution surface imaging microscopy without scanning near-field probes.
我们在优化的硅纳米结构薄膜表面上实验演示了亚衍射光图案，其周期可低至 150nm。我们使用近场和远场特性化，表明这种亚衍射图案可以通过改变照明角度来进行平移和旋转。可移动的高频光图案为无需扫描近场探针的亚衍射分辨率表面成像显微镜铺平了道路。
