Summary form only given. The enhancement of the light and matter interaction that can be obtained in periodic structures such as 1D photonic crystals or Fabry-Perot microcavities might be best used when the interaction considered is nonlinear. It has been theoretically shown that changes in the effective index of refraction of a dielectric material leading to large changes in reflection or transmission,...
Summary form only given. Photonic crystals are nanostructured materials that possess a periodic modulation of the dielectric constant. We have fabricated two-dimensional (2D) triangular photonic crystals in which one of the elements is a phthalocyanine (Pc) dye. These Pc's have a wavelength dependent absorption and large nonlinear absorption and nonlinear refraction coefficients. Thus, in our new...
Summary form only given. Ordered array of nanosize spheres are attractive for many linear and nonlinear applications. In particular, if one is able to tailor the nonlinear properties of the embedded material to the confining properties of its matrix, a substantial enhancement in the nonlinear optical properties is expected. Here we present results on the linear and nonlinear optical properties of...
