VTechWorks staff will be away for the Thanksgiving holiday starting Wednesday afternoon, Nov. 25, through Sunday Nov. 29, and will not be replying to requests during this time. Thank you for your patience.
Enhancement of second-order non-linear optical susceptibilities in organic film materials using non-centrosymmetric nanoparticles
A non-linear optical material comprising a plurality of non-centrosymmetric nanoparticles juxtaposed to non-linear optical (NLO) film at a localized surface Plasmon resonance (LSPR) of the nanoparticles. The LSPR is resonant at a wavelength of an incident light source, wherein a second-order non-linear susceptibility (χ(2)) of the NLO film with respect to the incident light is enhanced by the juxtaposition to the LSPR of the nanoparticles. The non-linear optical material lacks global inversion symmetry.
