微纳光学结构及应用
摘要:微纳光学结构技术是指通过在材料中引入微纳光学结构,实现新型光学功能器件。其中表面等离子体光学、人工负折射率材料、隐身结构,都是通过引入微纳结构控制光的衍射和传播,从而实现新的光学性能。从这个角度来讲,微纳光学结构的设计和制造是微纳光学发展的共性关键技术问题,微纳光学是新型光电子产业的重要发展方向。 =(hEr=f>7 z6Mf>q 关键字:微纳光学 ;纳米制造;微纳光学产业; qbT].,?!U .WtaU Abstract: Micro-nano optical structure technology refers to through the introduction of micro-nano optical structure in the material, implement new optical functional devices. The surface plasmon optics, artificial negative refractive index materials, stealth structure, through the introduction of micro-nano structure control of light diffraction and transmission, so as to realize the new optical performance. From this perspective, micro-nano optical structure design and manufacture is the universal key technical problems in the development of micro-nano optics, micro-nano optics is a new important development direction of optoelectronic industry.
