  1. 1. Optical Studies of Periodic Microstructures in Polar Materials

    Författare :Herman Högström; Carl Gustaf Ribbing; Clivia M. Sotomayor Torres; Uppsala universitet; []
    Nyckelord :Engineering physics; polaritonic; polar; photonic crystal; surface phonon polariton; multilayer; Reststrahlen; SiC; SiO2; Teknisk fysik;

    Sammanfattning : The optical properties of matter are determined by the coupling of the incident electromagnetic radiation to oscillators within the material. The oscillators can be electrons, ions or molecules. Close to a resonance the dielectric function exhibits strong dispersion and may be negative. LÄS MER

    Sammanfattning : The concept of photonic crystals was born in the late 1980's when two important letters were published that showed the possibility to control light propagation by a periodic structure. A photonic crystals consists of two or more materials with different dielectric functions periodically arranged on the length scale of light. LÄS MER
