我们提出了一种三维（3D）纳米级金属异质波导，用于纳米横截面中的光纳米引导。时域有限差分模拟表明，截面为35nmx55nm的光束可以有效地沿异质波导传播，能量损失为2.84dB/mum。由这种异质波导构建的3D纳米级马赫-曾德干涉仪和金属波导阵列显示出有趣的传感和阵列纳米聚焦特性，这意味着在纳米传感、纳米光刻、阵列成像和光流控制等纳米光子学领域的潜在应用。
We propose a three-dimensional (3D) nanoscale metal heterowaveguide for nanoguiding of light in nanometric cross section. Finite-difference time-domain simulation reveals that a light beam with 35nmx55nm cross section can effectively propagate along the heterowaveguides with 2.84dB/mum energy loss. 3D nanoscale Mach-Zehnder interferometers and metal waveguide arrays constructed by such heterowaveguides show interesting sensing and array nanofocusing properties, implying potential applications in the fields of nanophotonics such as nanosensing, nanolithography, array imaging, and controlling of the flow of light etc.
