Abstract

We report preliminary results on the development of compact (length < 100 microm) fiber-coupled dielectric-loaded plasmonic waveguide components, including Mach-Zehnder interferometers (MZIs), waveguide-ring resonators (WRRs) and directional couplers (DCs), whose operation at telecom wavelengths is controlled via the thermo-optic effect by electrically heating the gold stripes of dielectric-loaded plasmonic waveguides. Strong output modulation (> 20%) is demonstrated with MZI- and WRR-based components, and efficient (approximately 30%) rerouting is achieved with DC switches.

摘要

我们报告了紧凑型（长度<100微米）光纤耦合介质加载等离子体波导组件的初步开发成果，这些组件包括马赫曾德尔干涉仪（MZI）、波导环形谐振器（WRR）和定向耦合器（DC），它们在电信波长下的运行是通过对介质加载等离子体波导的金条纹进行电加热，利用热光效应来控制的。基于MZI和WRR的组件展示出了强烈的输出调制（>20%），而DC开关实现了高效（约30%）的重新路由。
