  1. Atom-photon Interactions In 1D Photonic Crystals: From cQED to band-gap physics

    05 Jan 2016 | | Contributor(s):: Jonathan Hood

    We investigate opportunities that emerge from the integration of cold atoms with nanoscopic photonic crystal waveguides (PCWs). PCWs enable the light-matter interaction to be engineered for both trapping and strong atom-photon coupling, thereby opening new avenues for novel quantum transport and...

  3. Slow and Fast Light - Penetrating the Fog

    16 Dec 2010 | | Contributor(s):: Jacob B. Khurgin

    Performance of optical delay lines and nonlinear devices based on slow wave propagation in photonic crystal waveguides in the presence of higher order dispersion is analyzed and compared with other slow light schemes, such as coupled resonators and media with electromagnetically-induced...

  4. Illinois iOptics Lecture 5: Deposited Nanorod Films for Biosensor Applications

    17 May 2010 | | Contributor(s):: Brian Cunningham

    Planar photonic crystals have been used as the basis of many biological sensing devices. Here, we successfully demonstrated that the combination of a photonic crystal structure and a dielectric nanorod coating prepared by the glancing angle deposition technique can lead to significant increases...

  5. Photonic Crystals via Confinement of Anisotropic Colloids

    02 Mar 2010 | | Contributor(s):: Mohammad Mayy, Chekesha Liddell

    Controlling light-matter interactions with materials structured at micron and submicron length scales has been predicted as the basis for enhancements in the performance of a range of technologies, including photovoltaics, sensors and solid state lighting devices. However, the types of...

  6. Linear and Nonlinear Optical Devices Based on Slow Light Propagation: Figures of Merit

    19 May 2008 | | Contributor(s):: Jacob B. Khurgin

    Performance of optical delay lines and nonlinear devices based on slow wave propagation in photonic crystal waveguides in the presence of higher order dispersion is analyzed and compared with other slow light schemes, such as coupled resonators, media with electromagnetically-induced...

  7. Three-Dimensional Photonic Crystals

    11 Feb 2008 | | Contributor(s):: Minghao Qi

    A photonic crystal (PhCs) is typically a composite of a high-dielectric-constant material (e.g. Si) and a low-constant one (e.g. SiO2 or air), arranged periodically in space. Two dimensional examples include a hexagonal lattice of air holes drilled in a Si slab, or a set of Si rods at square...
