Polychromatic nanofocusing of surface plasmons


In this work the authors introduce the concept of polychromatic plasmonics, and demonstrate the functionalities of a broadband plasmonic lens based on metal-dielectric-metal (MDM) structures. The authors utilize quadratic variation of the dielectric layer in the transverse direction to produce a parabolic optical potential which is practically wavelength… (More)
