基于近场倏逝波干涉原理的近场光学虚拟探针可用于光学数据存储、纳米光刻、近场光学成像和光学操控等领域。本文给出了近场虚拟探针光分布的数值模拟结果，并分析了虚拟探针对孔径、偏振等的依赖性。模拟结果表明，传输效率高于纳米孔径金属涂层光纤探针。当透镜与记录介质之间的距离在一定范围内增加时，虚拟探针的尺寸保持不变，从而可以放松近场系统中的临界纳米分离控制。
A near-field optical virtual probe based on the principle of near-field evanescent wave interference can be used in optical data storage, nanolithography, near-field optical imaging, and optical manipulation. This letter gives the numerical simulation results of the optical distribution of a near-field virtual probe and analyzes the dependence of the virtual probe’s on the aperture, the polarization, etc. The simulation results reveal that the transmission efficiency is higher than that of a nanoaperture metal-coated fiber probe. The size of the virtual probe is constant when the distance between the lens and recording media increases within a certain range so that the critical nanoseparation control in near-field system can be relaxed.
