Abstract

The arising 3D printing technologies open new possibilities for the production of optical devices, e.g. of optical waveguides. Using two-photon polymerization (2PP), arbitrary three-dimensional structures with resolution below the diffraction limit can be manufactured, thus allowing for new and versatile applications in photonics. Recent demonstration of phononic metamaterials using 2PP fabrication rely on homogeneous mechanical properties of the photopolymer. Thus, the state of polymerization can be used as process parameter to develop adaptable phononic crystals. Here we demonstrate an optical setup that combines Brillouin- and Raman-scattering experiments to measure the mechanical and chemical characteristics with respect to the polymerization state.
