Abstract : The goal of our research was to build an ultrafast all-optical switching device in a single mode polymer optical fiber. We have concentrated on both extensive processing and characterization studies. Activities included characterizing: refractive index profile of preform slices; concentration profiles of preform slices with optical absorption; loss properties of core fibers; nonlinear refractive index of bulk and single-mode fiber with various techniques; and demonstrate an all-optical switching device in a Sagnac geometry. We have successfully measured the loss in a single-mode fiber using the cut and measure technique and are applying transverse loss measurements to understand the roll of scattering in the total loss. We also characterized the refractive index profiles of preforms and found a step index as expected. The step index fiber can be made into a graded index fiber by initiating diffusion at elevated temperature. This may lead to lower loss fibers due to reduced interfacial scattering.
