【摘要】 近场光存储正迅速发展成为下一代光信息存储器的主流技术,而现在将表面等离子体激元在近场光学中的一些特性应用于超高密度光信息储存也是国际上的一个研究热点。本文以应用于超高密度近场光存储的表面等离子体增强型纳孔光探针为研究重点,对表面等离子体激元的物理机理进行了分析,模拟设计了单个纳米孔,纳米孔阵列及纳米孔外加光栅结构的纳米器件,在此基础上对器件制备工艺进行了深入的研究,通过对器件的测试与分析,发现表面等离子激元对纳米孔的透过光波长和透过光强度有一定的选择和增强作用,为实现T密度光存储奠定了基础。更多还原

【Abstract】 Near-field optical storage technology is a principal solution for the next generation optical information storage, some extraordinary properties of surface plasmons in near-field optical domain has received tremendous attention for its potential application in ultra-high density optical storage.This thesis emphasis on surface plasmons enhanced near-field optical probe for ultra-high density storage. The physical mechanism of surface plasmons is discussed, we simulated and designed single nano-hole, nano-hole array and nano-hole plus grating structure nanodevices, then researched the preparation process, tested and analyzed the optical properties for devices. The result denominate surface plasmons could affect the wavelength and intensity of transmission lights in some degree. That has significant foundation for achieving T-density optical storage in the future.更多还原
