Well-designed plasmonic nanostructures can concentrate light at sub-wavelength area and offer possibility to engineer and manipulate nanoscale light-matter interaction. In this talk, I will present recent progress in my research group, including the following four topics: (1) Conversion of guided optical modes in a complex plasmonic optical nanocircuit [1]. I will give details in the design, fabrication, detection and analysis of the plasmonic nanocircuits. (2) Surface plasmon-enhanced circular dichroism [2] and (3) Optical manipulation of particles using well-designed plasmonic optical near fields. This part would include our recent works on sub-wavelength optical lattice [3], bi-functional plasmonic Archimedes' spiral trap [4] and the latest unpublished results on simultaneous trapping and chiral analysis. Finally, I will present our recent results on the modulation of two-photon photoluminescence of gold due to antenna eigenmodes [5].
