We report on a waveguide composed of a cascade of gain-enabled quantum dots with subwavelength dimensions. Fabrication is demonstrated through DNA-mediated self-assembly and a two-layer molecular self-assembly process that enables rapid prototyping. The device, which is identified with fluorescence microscopy and tested by optical near field detection, allows optical signal transfer at a well-defined wavelength in flexible routing geometry, such as straight paths and 90 degrees bends. The structure serves as a critical building block for nanophotonic systems with high integration density.
我们报道了一种由具有亚波长尺寸的级联增益量子点组成的波导。通过DNA介导的自组装和两层分子自组装过程展示了其制造方法，该过程能够实现快速原型制作。该器件通过荧光显微镜识别并通过光学近场检测进行测试，能够在诸如直线路径和90度弯曲等灵活的路由几何结构中以明确的波长进行光信号传输。该结构是具有高集成密度的纳米光子系统的关键构建模块。
