We present an extension of the rigorous coupled-wave analysis technique to analyze second-harmonic generation (SHG) in periodic optical nanostructures in the undepleted-pump approximation. We apply this method to analyze SHG in two example nanostructures for which we predict enhanced nonlinearity due to transverse near-field localization of the fundamental optical field in the nonlinear materia...

Nanostructures have considerably higher surface areas than their bulk counterparts; thereforesurfaces often play important, sometimes even dominant, roles in the nanostructure properties. Thenanocrystalline and nanotubes have low band gaps and high carrier mobility, thus offeringappealing potential as absorption gas. Interaction between methanol molecules and carbonnanotube is investigated usin...

Multifunctional porous Si nanostructure is designed to optically monitor enzymatic activity of horseradish peroxidase. First, an oxidized PSi optical nanostructure, a Fabry-Pérot thin film, is synthesized and is used as the optical transducer element. Immobilization of the enzyme onto the nanostructure is performed through DNA-directed immobilization. Preliminary studies demonstrate high enzyma...
