  2. 21. Fabrication of inverse opal oxide structures for efficient light harvesting

    Author : Delphine Lebrun; Lars Österlund; Gunnar Niklasson; Vassilios Kapaklis; Herman Högström; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photonic; inverse opal; metal oxide; opal; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

    Abstract : Artificial opals are self-assembled face centered cubic (fcc) structures of  spherically shaped beads, which interesting applications as photonic band gap materials. Inverse opals are photonic crystals consisting of fcc paced voids of a low refractive index material imbedded in a high refractive index material. READ MORE

  4. 22. Free-space cavity optomechanical systems on a chip with III-V heterostructures

    Author : Sushanth Kini; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optomechanics; Micromechanical resonators; Cavity Optomechanics; III-V materials; Photonic crystals;

    Abstract : Cavity optomechanics examines the mutual interaction between light and mechanical motion for controlling mechanical resonators down to the quantum regime. A major challenge in the field of cavity optomechanics remains accessing a strong interaction between the light field and mechanics on the level of single quanta. READ MORE

  5. 23. Photonic Qubits for Quantum Communication : Exploiting photon-pair correlations; from theory to applications

    Author : Maria Tengner; Anders Karlsson; Alexei Trifonov; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum communication; photon-pair sources; entanglement; Physics; Fysik;

    Abstract : For any communication, the conveyed information must be carried by some physical system. If this system is a quantum system rather than a classical one, its behavior will be governed by the laws of quantum mechanics. READ MORE

  6. 24. Templating and self-assembly of biomimetic materials

    Author : Christian Mille; Lennart Bergström; Mika Linden; Stockholms universitet; []
