Near-field Nano-optics

我们已经开发了大量的近场纳米光学探头，以实现高光学吞吐量、高空间分辨率、包括AFM、STM和FFM传感、集成以及通过逝去的光子检测力的混合功能。用新的探头进行的实验结果是相当成功的。开发了基于真实感三维模型的计算机仿真程序，并将其应用于光学近场电磁场的分析和NSOM成像的仿真。在材料科学和生物科学领域的应用一直受到重视。给出了DNA和染色体的高分辨率图像。量子纳米结构的发射观测取得了很大的进展。在工程上，利用光致变色材料实现了超高密度光数据存储和光致变色材料表面的超精细加工。近场力效应用于建立非自组织光学显微镜，采用激光捕获探头和原子引导，并通过小孔进行运动控制。此外，在近场图像观测、光谱分析、制造和光子力动力学等方面的应用也是成功的。

We have developed lots of probes for Near-field Nano-optics to realize high optical throughput, high spatial resolution, hybrid functions including AFM, STM, and FFM sensing, integration, and the detection of force through evanescent photons. The experimental results with the new probes are fairly successful. A computer simulation program based on a realistic 3D model has been developed and been applied to the analysis of the electromagnetic field in optical near-field and the simulation of NSOM imaging. Applications have been stressed on the fields of material science and bio science. High resolution images of DNAs and chromosomes are given. A great progress was made on the observation of emission from quantum nanostructures. In engineering, super dense optical data storage using photochromic materials and super fine fabrication of the surface of photo resisting materials have been realized. Near-field force effect is used for establishing a NSOM using a laser-trapped probe and atom guidance, and the movement control through small apertures. Moreover, applications in image observations, spectroscopy and analysis, fabrication, and photon-force dynamics in near-field are successful.
