Abstract
Composite organic-polymer glass optical waveguides in which coupling to the nonlinear organic-polymer layers was achieved by excitement of the underlying ion-exchanged glass waveguide and coupling of the light to the organic-polymer layer were fabricated and measured. A picosecond pulsed color center laser (λ = 1.5 μm) was used to measure the third-order optical susceptibility χ(3)(−w; w, −w, w) in an organic-dye-polymer composite glass waveguide with a Mach–Zehnder interferometer. For a squarylium-dye-doped poly(methyl methacrylate)–styrene-acrylonitrile matrix polymer layer, a composite χ(3) of roughly 90, in units of χLiNbO3(3), was measured.
