Paper Abstract

We describe an experimental investigation of the nonlinear optical properties of nanocomposites incorporating organic (hyperbranched polymer)-metallic (Au or Pt) nanoparticle complex embedded in polymer films. Zscan techniques are employed to measure the effective third-order nonlinear optical susceptibilities χ(3) eff of the composites with 35 ps pulses at 532 nm. The relative sign of the real and imaginary parts of χ(3) eff could be explained qualitatively by the Kramers-Kronig relation. The third-order nonlinear optical susceptibilities of Au and Pt nanoparticles from the measured values for χ(3) eff were also determined to be (-5.48 + 4.76i)×10-8 and (4.43 - 0.65i)×10-6 esu, respectively, at 532 nm.
