A novel approach to manipulating multiple optical signals at subwavelength scale is proposed in dendritic organic/metal nanowire heterostructures. The heterostructures are prepared by embedding Ag nanowires in fac-tris(2-phenylpyridine) iridium microwires during the self-assembly in liquid phase. Optical signals inputted from the organic waveguide can be selectively transferred to the predetermined subwavelength output ports based on the angular dependence of the photon-plasmon coupling.
在树枝状有机/金属纳米线异质结构中提出了一种在亚波长尺度上操纵多个光学信号的新方法。该异质结构是通过在液相自组装过程中在 fac-tris(2-苯基吡啶)铱微米线中嵌入 Ag 纳米线制备的。基于光子-等离子体耦合的角度依赖性，从有机波导输入的光学信号可以选择性地传输到预定的亚波长输出端口。
