用于可见光量子发射器的单晶银等离子体电路

A single-crystalline silver plasmonic circuit for visible quantum emitters

Christian Schörner, Subhasis Adhikari, Markus Lippitz

摘要:

等离子体激元波导是纳米光子器件中的关键元件,其用作纳米级光源和检测器之间的光学互连。等离子体双线传输线中的多模操作为近场操纵和信息编码提供了重要的自由度。然而,由于欧姆损耗,金纳米结构中的高度受限的等离子体激元传播通常限于近红外区域,排除了来自等离子体激元电路的所有可见量子发射体。在这里,我们报告自上而下的制造复杂的等离子纳米结构的单晶银板。我们展示了一个小的合奏的荧光团的一组波导模式和发射的可见光发光到波导的高效率的控制远程激发。这种方法开启了复杂等离子体波导和可见光谱范围内各种量子发射器之间纳米级光-物质相互作用的研究。

英文摘要:

Plasmonic waveguides are key elements in nanophotonic devices serving as optical interconnects between nanoscale light sources and detectors. Multimode operation in plasmonic two-wire transmission lines promises important degrees of freedom for near-field manipulation and information encoding. However, highly confined plasmon propagation in gold nanostructures is typically limited to the near-infrared region due to ohmic losses, excluding all visible quantum emitters from plasmonic circuitry. Here, we report on top-down fabrication of complex plasmonic nanostructures in single-crystalline silver plates. We demonstrate controlled remote excitation of a small ensemble of fluorophores by a set of waveguide modes and emission of the visible luminescence into the waveguide with high efficiency. This approach opens up the study of nanoscale light-matter interaction between complex plasmonic waveguides and a large variety of quantum emitters available in the visible spectral range.
