Beam shaping using a chain of photonic nanojet induced plasmonics

Abstract

Photonic nanojet arises from a microcavity leading to high electric field. On the other hand, metal nanoparticles (NPs) lead to high field due to localization in small volumes. In this work, PNJ from an array of cavity induced plasmon resonances has been studied. The sharp profile of the PNJ has been observed by the inclusion of NPs.
