Super luminescent Diode (SLD) with a new structure is proposed in which light is guided by surface plasmon waveguide (SPWG) rather than by the conventional dielectric waveguide. This results in a great increase of the spontaneous emission coupling. Other parameters important to the device operation such as the confinement factor, waveguide loss and waveguide facets reflectivities are also considered. It is shown that the new design outperforms the conventional ones using dielectric waveguides in both the output power and optical spectral width.
提出了一种具有新结构的超发光二极管（SLD），其中光由表面等离子体波导（SPWG）而非传统的介质波导引导。这导致自发发射耦合大幅增加。还考虑了对器件运行很重要的其他参数，如限制因子、波导损耗和波导端面反射率。结果表明，在输出功率和光谱宽度方面，新设计均优于使用介质波导的传统设计。
