摘要:
二维亚波长周期结构金属薄膜具有光透过率异常增强的现象,某些情况下,这种薄膜的峰值透过率比根据传统小孔理论计算的预测值高3个量级.这种结构的金属薄膜在光印刷、近场显微镜和光子器件等方面有着广泛的应用前景,近年来引起了人们的重视.根据目前的实验研究报道,这种周期结构金属薄膜通常利用聚焦离子束刻蚀工艺来获得,器件的光学响应在可见光波段和近红外波段.利用镂空模板法制备了周期结构金属薄膜.实验表明,制得的器件在红外波段也具有透过率异常增强的现象,且利用这种方法易于获得大面积对称结构和串联结构的器件.
Abstract:
M eta l film sw ith two-d im ensiona l period ic array s o f sub-wave leng th apertures can exh ibit extraordinary opt-i cal transm ission. In som e cases, the transm ission enhancem en t can be three o rders of magnitude greater than what is predicted by the standa rd aperture theory. There has been a great interest in such structured film s due to its potentia l applications in pho tolithography, near fie ld m icro scopy and pho ton ic dev ices. In m ost o f the exper im ents repo rted to date, the per fo ra ted m eta l film s w ere fabricated by the focused- ion-beam m ethod, and the ir transm iss ion enhancem ent w as in the v isib le and nea r- infrared reg ions. Accord ing to our research, a stencilm ask m ethod can be used to fabr-i cate such pe rfora ted m eta l film s. Ou r expe rim en ts dem onstrated tha t the dev ices m ade w ith th is m ethod can also induce transm ission enhancem ent in the m idd le- in frared reg ion. Mo reover, larg e- sca le and the cascaded structures can be easily obta ined by ourm ethod.
