Paper Abstract

Recently, dielectric loaded surface plasmons (SPs) elements are inducing highly interesting in the field of nanooptics, which are composed of dielectric nanostructures fabricated on a metallic thin film. This configuration will provide a route to novel integrated micro-optical devices and components combining photonics and electronics on the same chip. The advantages are easy fabrication, easy integration, and also the potential to realizing active plasmonic devices. In this talk, we will present our recent work in this field. Polymer (PMMA) nano-structures are fabricated on a silver film by the electron beam lithography (EBL) and laser interference lithography. These nano-structures are used to manipulate the behaviors of the SPs, such as converging, diverging, and guiding the propagation of SPs in subwavelength scale. Except for the pure PMMA nano-structures, dye materials (Rhodamine B, RhB) doped PMMA structures are also fabricated on the silver film. The RhB molecules will work as the active medium to excite the SPs or compensation the loss of SPs wave. The dye doped PMMA nanostructure provides a choice to realize active plasmonic elements, such as SPs Bragg gratings. On the other hand, the interaction between the fluorescence molecules and SPs will give rise to some new optical phenomena, such as directional fluorescence emission, anisotropic fluorescence emission. These polymer based plasmonic structures are investigated with a home-built leakage radiation microscopy (LRM).
