Gold Nanoparticles on Waveguides For and Toward Sensing Application

摘要: First, a short overview of the sensor activities on surface plasmon waveguide mode coupling via wave vector match in metal-coated channel waveguides as well slab and optical fibers is given. Both monomode multimode approaches were demonstrated implementation Bragg gratings hollow are described. Then, use gold nanoparticles for application combination with these device systems discussed. At beginning, approach described without taking typical features into account. devices, which localized resonance, an absorption band, intrinsic to nanoparticles, color changes colloids upon clustering operation This achieved quasi-waveguides, waveguides, fibers. Transmission reflectance experiments have been performed, either spectral information or monochromatic light pure intensity information. An electro-optical The photonic crystal planar-waveguide fiber bundles.
