报告摘要：Plasmonics has garnered tremendous research interests because of the unique capability of light manipulation down to subwavelength or even deep subwavelength scale. However, as the considerable plasmon damping originating from the intrinsic ohmic loss, noble metal plasmonic nanostructures have long been suffering from high optical loss, which severely deteriorate the device performance. In this talk, we will present our recent investigations on how to fighting with plasmonic optical losses. On the one hand, we have been developing a couple of low loss non-noble metal plasmonic metals to compromise the inherent trade off between optical losses and field concentration, aiming at provide alternative solutions to low loss integrated optics beyond noble metals. On the other hand, we have designed emerging hierarchical plasmonic meta-structures to boost broadband light harvesting of metallic materials, based on which we have enabled a couple of precise photothermal manipulations beneficial for solar desalination, in-situ photodetection and anti-detection, etc. We expect that these results would inspire new insights on low loss plasmonics and/or pay new routes towards metamaterial-based point-of-use applications.
