未来的光数据传输模块需要集成10000 × 10000以上的输入输出通道，以提高数据传输速率和容量。这种集成水平大大超过了传统的衍射限制光子集成电路，将需要使用低于衍射限制的模式约束波导，并且还需要将这些波导与衍射限制元件集成（1,2）。我们提出将多个银纳米线等离子体波导与聚合物光波导集成在芯片上，用于纳米尺度的光约束和导光。在我们的装置中，纳米线垂直于聚合物波导，一端在聚合物内。我们从理论上预测和实验上证明了来自同一波导的光耦合到多个纳米线中，并通过改变光的偏振来控制耦合程度。
Future optical data transmission modules will require the integration of more than 10,000 x 10,000 input and output channels to increase data transmission rates and capacity. This level of integration, which greatly exceeds that of a conventional diffraction-limited photonic integrated circuit, will require the use of waveguides with a mode confinement below the diffraction limit, and also the integration of these waveguides with diffraction-limited components(1,2). We propose to integrate multiple silver nanowire plasmonic waveguides with polymer optical waveguides for the nanoscale confinement and guiding of light on a chip. In our device, the nanowires lay perpendicular to the polymer waveguide with one end inside the polymer. We theoretically predict and experimentally demonstrate coupling of light into multiple nanowires from the same waveguide, and also demonstrate control over the degree of coupling by changing the light polarization.
