Reconfiguraable Plasmofluidic Lenses and Plasmonics-Enhanced Optomechanics -- Plasmonics has become an important branch in nano optics, which focuses on the intriguing phenomena and unique applications of surface plasmons occurring in metallic nanostructures. In particular, plasmonics allows us to manipulate light at the truly nanoscale, promising next-generation optical devices, efficient energy harvesting, and ultra-sensitive biomedical detection. In this talk, I will present the first demonstration of reconfigurable plasmonic lenses operating in microfluidic environment, which can dynamically diverge, collimate and focus surface plasmons. I will also discuss how plasmonics constructively interferes with mechanics. Strong optical forces and torques can be achieved by rationally designed plasmonic nanostructures.
