Rapid Laser Prototyping Of Polymer-Based Nanoplasmonic Components
Renewed and growing interest in the field of surface plasmon polaritons (SPPs) comes from a rapid advance of nanostructuring technologies. The application of two-photon polymerization technique for the fabrication of dielectric and metallic SPP-structures, which can be used for localization, guiding, and manipulation of SPPs waves on a subwavelength scale, is studied. This technology is based on nonlinear absorption of near-infrared femtosecond laser pulses. Excitation, propagation, and interaction of SPP waves with nanostructures are controlled and studied by leakage radiation imaging. It is demonstrated that created nanostructures on metal film are very efficient for the excitation and focusing of SPPs. Examples of passive and active SPP components are presented and discussed.
