The recent developments in the fabrication and characterization of plasmonic nanostructures have stimulated continuous effects in the search for their potential applications in the photonic fields. In this review article an international team of researchers (India, USA – Vanderbilt University, San Diego State University, Canada) concentrated on the role of plasmonics in photonics, covering recent advances in ultrafast plasmonic materials with focus on all-optical switching. They discussed fundamental phenomena of plasmonic light–matter interaction and plasmon dynamics elaborating on the ultrafast processes unraveled by both experimental and theoretical methods, along with a comprehensive illustration of leveraging ultrafast plasmonics for all-optical switching and pulse laser generation with a focus on device design and performance. They provided a brief highlight of the current progress and the potential future directions in ultrafast plasmonics… read more. Open Access TECHNICAL ARTICLE
