Paper Abstract

A new technique, ultrafast refractometry, is introduced for probing the refractive, absorptive, and diffractive conditions in nanocomposite assemblies. It is shown that the physical characteristics of nanocomposites-nanoparticle sizes and volumetric ratios in the polymer host-are decisive factors in determining the material's overall optical properties. Ultrashort optical pulses (100 fs) act as an in-situ probe for temporal phase, optical attenuation, and spatial coherence in these discrete materials. This technique is demonstrated for numerous samples of 20 nm SiC nanoparticle/polymer nanocomposites. A close link between the physical properties and the ultimate refraction, absorption, and diffraction characteristics of these nanocomposite optical materials is shown.
