Using a finite-element, full-wave modeling approach, we present a flexible method of analyzing and simulating dielectric and plasmonic waveguide structures as well as their mode coupling. This method is applied to an integrated plasmonic circuit where a straight dielectric waveguide couples through a straight hybrid long-range plasmon waveguide to a uniformly bent hybrid one. The hybrid waveguide comprises a thin metal core embedded in a two-dimensional dielectric waveguide. The performance of such plasmonic circuits in terms of insertion losses is discussed.
我们采用有限元全波建模方法，提出了一种灵活的方法来分析和模拟介质与等离子体波导结构及其模式耦合。该方法应用于一个集成等离子体电路，其中直的介质波导通过直的混合长程等离子体波导与均匀弯曲的混合波导耦合。混合波导包括嵌入二维介质波导中的薄金属芯。讨论了这种等离子体电路在插入损耗方面的性能。
