利用泄漏辐射显微镜（LRM）研究了布洛赫表面波在图像化多层材料上的侧向约束。纳米聚合物波导阵列是在标准玻璃盖上生长的适当的氮化硅/氧化硅多层材料上制造的。利用聚合物的功能特性，荧光蛋白被接枝到波导上。直接和傅里叶成像平面的荧光LRM分析表明，大量发射的辐射耦合到引导模式，然后传播到纳米波导中。模态的观测结果得到了数值模拟的支持。(C) 2012年美国物理研究所。(doi: 10.1063/1.3684272)
The lateral confinement of Bloch surface waves on a patterned multilayer is investigated by means of leakage radiation microscopy (LRM). Arrays of nanometric polymeric waveguides are fabricated on a proper silicon-nitride/silicon-oxide multilayer grown on a standard glass coverslip. By exploiting the functional properties of the polymer, fluorescent proteins are grafted onto the waveguides. A fluorescence LRM analysis of both the direct and the Fourier image plane reveals that a substantial amount of emitted radiation couples into a guided mode and then propagates into the nanometric waveguide. The observations of the mode are supported by numerical simulations. (C) 2012 American Institute of Physics. [doi:10.1063/1.3684272]
