control of nano-size light with plasmonic waveguide structure

我们研究了等离子体激元器件，如分束器、谐振器、干涉仪和调制器，以及提高等离子体波与光在体中传输的耦合系数。特别是，我们展示了具有高Q因子的微小等离子体谐振器。我们还提出了设计等离子体激元器件，以防止由于等离子体激元的传播长度和器件结构的无意缺陷而导致的器件性能退化。

We have studied on the plasmonic devices, eg, splitters, resonators, interferometers and modulators, and improvement of the coupling coefficient between plasmon wave and light propagating in bulk. Especially, we demonstrated tiny plasmonic resonator with high Q factor. We have also presented that we should design the plasmon devices to prevent degradation of device performance owing to the propagation length of plasmon and unintentional imperfection of the device structure.
