Optical nonlinearities of nanocomposite constituents selectively addressed by polarization‐controlled coherent anti‐Stokes Raman scattering

Abstract

Polarization coherent anti-Stokes Raman scattering (CARS) is shown to provide a means to selectively and independently address optical nonlinearities of materials constituting a multicomponent nanostructure, thus suggesting the way to tailor the nonlinear-optical response of nanocomposite materials. Polarization properties of CARS in porous glass infiltrated with a toluene solution are experimentally studied. Rotation of the polarization analyzer with respect to the polarization vectors of the linearly polarized pump fields is shown to radically modify CARS line profiles, indicating changes in the ratio of CARS signal components related to toluene molecules and the porous glass host.

“…Photonic crystal fibers have also been used for the generation of a dispersion-compensated supercontinuum for use as the Stokes laser source in ultrabroadband multiplex CARS. 134 Another approach for observing CARS is to use 'noisy' light. A theoretical description of nano-CARS has also been given by the same author.…”

“…Polarization-CARS was used to study a toluene solution infiltrated in a porous glass matrix. [155] The experimental method could selectively and independently address optical nonlinearities of the materials. The rotation of the polarization analyzer with respect to the polarization vectors of the linearly polarized pump fields was found to result in significant deformations of the CARS line profiles.…”
