在相干光纤束的远端面上形成纳米尺寸光学孔的有序阵列。来自SNOM探头技术的制造步骤允许产生具有可调节尺寸的高密度孔阵列，该阵列保留了束的初始结构。此外，每个光学纳米孔周围都有一个金环状的纳米电极。通过该阵列传输的光强的远场角分布呈现出与孔径大小有关的衍射行为。这一分析证明了它作为近场光学阵列的潜在用途。因此，这样的阵列通过将在纳米和微米尺度上伴随获得的信息相互关联而起到桥梁作用。此外，由于纳米环电极具有良好的电化学性质，可以将其与电化学等正交技术相结合来完成近场光学信息的提取。
An ordered array of nanometer-sized optical apertures is created on the distal face of a coherent optical fiber bundle. The fabrication steps derived from SNOM probes technology allowed to produce a high-density array of apertures with adjustable dimensions which retains the initial architecture of the bundle. Moreover, each optical nanoaperture is surrounded by a gold ring-shaped nanoelectrode. The far-field angular distribution of light intensity transmitted through the array shows a diffracting behavior which is a function of the aperture sizes. This analysis demonstrates its potential use as a near-field optical array. Such an array plays therefore a bridging role by interrelating information obtained concomitantly at the nanometer and micrometer scales. Furthermore, since the nanoring electrodes show excellent electrochemical properties, the near-field optical information can be completed by combining it with an orthogonal technique, such as electrochemistry.
