摘要:

本文报道了在布拉格反射镜背反射中获得的具有近1可见度和半波长周期性的表面等离子体激元(SPP)干涉条纹的实验观察。基于泄漏辐射显微镜(LRM)的方法代表了光学近场分析的另一种解决方案,并为SPP条纹的定量分析开辟了新的途径。利用LRM研究了各种SPP干涉图样,并与理论模型进行了比较,分析了布拉格镜的高反射率。

英文摘要:

We report the experimental observation of surface plasmon polariton (SPP) interference fringes with near-unity visibility and half-wavelength periodicity obtained in back reflection on a Bragg mirror. The presented method based on leakage radiation microscopy (LRM) represents an alternative solution to optical near-field analysis and opens new ways for the quantitative analysis of SPP fringes. With LRM we investigate various SPP interference patterns and analyze the high reflectivity of Bragg mirror in comparison with theoretical models.
