Light-Matter Interaction at the Nanoscale with Plasmonic Vortices
Abstract
The combination of ideas from optics and solid state physics is helping better understandbasic principles of light-matter interacti on at the nanoscale and the creation of new devices fortechnology. This is the case of the emerging field studying the interplay be tween plasmonicsand optical vortices.Optical vortices are highly inhomogeneous electromagnetic field with quite unusualproperties , such as: i) a strong field s component in the propagation direction, ii) topologicaldistinct classes, and iii) a defined orbital (OAM) and spin (SAM) angular momenta. They havebeen shown to produce atypical effects in their interaction with matter, and are pr omising inapplications in several fields, including spintronics and quantum information.Plasmons are dielectric-metal interface ex citations that can propagate in 2D or be localizedin small particles. Their energy-momentum dispersion relation deviates significan tly from thatof light in dielectric media, exhibiting new interesting phenomena that lead to applications.
