Development of Silica Fibers and Microstructures with Large and Thermodynamically Stable Second Order Nonlinearity

Abstract

Summary: During the last four years, we have accomplished the following goals. * We have developed the theoretical framework for the analysis of second-order nonlinearity in the proposed nonlinear fibers and microspheres. * We have experimentally demonstrated second harmonic generation in the proposed nonlinear fibers and established good agreement between theoretical predictions and experimental measurements. * We have obtained preliminary results that can achieve intermodal phase matching as well as quasi-phase matching based on plasmonic enhancement. * We have established that microspheres covered with nonlinear polymers and plasmonic nanoparticles can maintain high Q whispering gallery modes.
