摘要

Light-matter interaction realized by plasmonic microstructures brings about a strong light confinement,which means energy can be controlled under micro-or nano-scale,providing a versatile approach to tailor optical properties precisely.However,a large Ohmic loss is inevitable in the plasmonic formations,and usually leads to the thermal instability and low efficiency of designed devices.For common plasmonic nanostructures,it is difficult to have the ability of energy confinement and low Ohmic loss simultaneously.
