The Development and Application of Multifunctional Plasmonic Nanoantennas  

 
Kimani C. Toussaint, Jr. 
 
Professor and Senior Associate Dean of Engineering at Brown University
 
Abstract:
Plasmonic nanoantennas are attractive for a variety of potential applications in nanotechnology, biology, and photonics due to their ability to tightly confine and strongly enhance optical fields. In recent years, our group, the PROBE Lab, has made significant contributions in plasmonic nanoantenna technology by more closely exploring the rich parameter space associated with these structures. This talk will discuss our work with arrays of Au bowtie nanoantennas (BNAs) with an emphasis on harnessing their field enhancement properties for improved manipulation of microparticles. In addition, we will present some unique features of BNAs when they are supported on high-aspect ratio pillars. Aside from the particle manipulation features that these pillar-supported BNAs (pBNAs) share with their substrate-bound counterparts, the use of pBNAs to record the optical near field and create planar optical elements will also be discussed. The talk will conclude with a discussion of some future prospects for nanoantenna technology.
