TaCoNa-Photonics 2010Light Localization in a Random Configuration of Dielectric NanocolumnsYuta Inose1,2, Masaru Sakai3, Kazuhiro Ema1,2,4, Akihiko Kikuchi1,2,4, Katsumi Kishino1,2,4, Tomi Ohtsuki1,2,41Sophia University, Japan 2CREST, Japan Science and Technology Agency, Japan 3University of Yamanashi, Japan 4Sophia Nanotechnology Research Center, Sophia University, Japan Abstract: We present frequency dependence of Anderson localization of light in finite-sized two-dimensional random systems. We have investigated time variation of total energy within a system composed of dielectric columns, by adopting parameters of actual nano-sized semiconductor crystals with a high filling fraction of the columns. We have succeeded in obtaining single parameter scaling of the localization effect. In addition, we show that the frequency dependence of the localization in the system depends on the degree of wave interference due to Bragg-like diffraction, rather than on the magnitude of the light scattering cross section for a single column.
