Effective permittivity and optical properties of photonic/plasmonic structures in glass — •Oleksiy Kiriyenko, Wolfram Hergert, Stefan Wackerow, and Heinrich Graener — Martin-Luther-Universität Halle-Wittenberg, Institut für Physik, Friedemann-Bach-Platz 6, 06108 Halle

Nanocomposite glass containing metallic nanoparticles are of considerable interest as photonic structures with special optical properties. The effective dielectric properties of such nanocomposite glass has to be known first for a successful calculation of optical properties of photonic/plamonic structures in this material. The finite element method (FEM) is used to calculate the complex effective permittivity of two-phase disordered composite media consisting of silver nanoparticles which are randomly placed in a homogeneous dielectric (glass). Volume fractions know from experiments are studied. The results are compared with effective medium theories (EMT). The results are used to calculate optical properties of photonic structures generated in such material. The calculations are compared with experimental results.
