| Research Abstract |
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.
