We report the experimental realization of horizontal plasmonic slot waveguides capable of subdiffraction modal confinement at IR wavelengths. These waveguides have a propagation length of approximately 6 lambda(g) and are monolithically integrated with conventional silicon photonic waveguides on the same silicon-on-insulator platform. Direct coupling of light from the silicon waveguides to the plasmonic waveguides was achieved with an efficiency of 30% using taper-funnel couplers to obtain mode matching between the two waveguide systems.
我们报告了在红外波长下能够实现亚衍射模限制的水平等离子体槽波导的实验实现。这些波导的传播长度约为 6λ(g)，并且与相同的绝缘体上硅平台上的传统硅光子波导单片集成。使用锥形漏斗耦合器实现了从硅波导到等离子体波导的光的直接耦合，效率为 30%，以获得两个波导系统之间的模式匹配。
