Controlled coupling of nanoparticles to polymer-based photonic structures

Abstract : In this study, we investigate theoretically and experimentally the nanoparticles/photonic structures coupling. In detail, the work focuses on the elaboration and applications of structured polymer materials, as well as the manipulation of optical properties of various kinds of nano-objects such as gold nanoparticles, magnetic and nonlinear nanoparticles, etc. The coupling of each kind of nanoparticles addresses a specific goal. In order to conduct research, we first build and test an optical confocal setup, which allows us to both image and fabricate nanostructures at a sub-lambda resolution. Besides, we propose a method exploiting the thermal effect caused by a continuous-wave laser source to optimize 2D and 3D structures realized by low one-photon absorption (LOPA)-based direct laser writing (DLW). Then by using this technique, we are capable of precisely determining the position and embedding various kinds of nanoparticles (gold nanoparticles, nonlinear nanoparticles, and magnetic nanoparticles) into arbitrary polymeric photonic structures. The characterization of the fabricated structures is carried out using the same confocal setup. We demonstrate a good enhancement of the optical properties of the nanoparticles embedded inside photonic structures. We also perform numerical calculations by using a FDTD method to confirm the experimental results.
