Plasmon-assisted photonics at the nanoscale

Abstract

Plasmons are collective oscillations of electrons that have been exploited in many applications by manipulating and guiding light at resonant frequencies. The transition from understanding the origin and fundamentals of surface plasmon resonance to its many revolutionary applications has been intriguing. Advances in nanofabrication techniques over the last few years have led to variety of applications such as high-resolution plasmon printing, nanoscale waveguides, biodetection at the single-molecule level and enhanced transmission through sub-wavelength apertures, which are all examples of plasmon-assisted nanophotonics. Fundamental aspects of the surface plasmon resonance underlie enticing applications in nanophotonics.
