Longitudinal shaping of subwavelength infrared beams using plasmonic bull's-eye structure with concentric slits

Research output: Chapter in Book/Report/Conference proceedingConference contributionAcademicpeer-review

Abstract

We report a bull's-eye gold nanostructure, which focuses infrared beams into subwavelength spots with the ability to shape the longitudinal intensity profile and the focal length, thus addressing many challenges in label-free imaging, nanolithography, and biomedical applications.
