Abstract

Fueled by the rapid pace of technological advancements, the convergence of ideas from optics and solid-state physics is yielding valuable insights into the fundamental principles governing interactions between light and matter at the nanoscale, as well as paving the way for future technologies. In this review, we explore a burgeoning avenue that investigates the synergy between plasmonics and optical vortex concepts. The excitation of plasmon modes with phase dislocations, occasionally referred to as plasmonic vortices, has revealed novel facets of physics. One particularly promising expansion of this field pertains to the manipulation of nearby nanostructures. Consequently, we provide commentary on the associated research, which offers innovative solutions to a variety of technological challenges.
