Rapid laser direct writing of plasmonic components

Abstract

A new device named technology-plasmonics has recently emerged and can be used to manipulate light at the nanoscale level. Here, we report the method of two-photon photopolymerization for rapid laser direct writing of plasmonic components. The characterization of these components is performed by a leakage radiation microscope, which has the same system construction as the two-photon photopolymerization micro-fabrication system except the laser pattern. The dielectric structures covered with gold proved to be very efficient for the excitation of surface plasmon polaritons in this system and can achieve different plasmon fields
