A type of a plasmonic waveguide has been proposed featuring an "open" design that is easy to manufacture, simple to excite and offers convenient access to a plasmonic mode. Optical properties of photonic bandgap (PBG) plasmonic waveguides are investigated experimentally by leakage radiation microscopy and numerically using the finite element method confirming photonic bandgap guidance in a broad spectral range. Propagation and localization characteristics of a PBG plasmonic waveguide have been discussed as a function of the wavelength of operation, waveguide core size, and the number of ridges in the periodic reflector for fundamental and higher order plasmonic modes of the waveguide.
已经提出了一种等离子体导波结构，其具有“开放”设计，易于制造，易于激发并且便于获得等离子体模式。通过泄漏辐射显微镜实验和使用有限元方法的数值研究，研究了光子带隙（PBG）等离子体导波的光学特性，在很宽的光谱范围内证实了光子带隙导光。讨论了 PBG 等离子体导波的传播和局域特性作为工作波长、波导芯尺寸以及周期性反射器中脊的数量的函数，对于导波的基本和更高阶等离子体模式。
