  2. 1. Diffractive Optics Design

    Author : Jörgen Bengtsson; Chalmers University of Technology; []
    Keywords : computer-generated waveguide hologram; diffractive optics; fan-out; millimeter wave radiation; proximity effect; optimal-rotation-angle method; kinoform; integrated optics; beam shaping; outcoupling grating; scalar optics;

    Abstract : Diffractive optical elements (kinoforms) change the way light propagates, and can perform very complex tasks. They can split an incident beam into any number of outgoing, and possibly focused, beams (fan-out). READ MORE

  4. 2. Manipulation of Light with Transformation Optics

    Author : Wei Yan; Min Qiu; Niels Asger Mortensen; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; transformation optics; Maxwell’s equations; invisibility cloaks; compensated bilayer; perfect imaging; optical illusion; nihility media; α media; Optics; Optik;

    Abstract : Transformation optics, a recently booming area, provides people a new approach to design optical devices for manipulating light. With transformation optics, a lot of novel optical devices are proposed, such as invisibility cloaks, optical wormholes, optical black holes, illusion devices. READ MORE

  5. 3. Quantum Optics and Quantum Information Processing in Rare-Earth-Ion-Doped Crystals

    Author : Nicklas Ohlsson; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Rare-earth ions; Optical processing; Optical storage; Electromagnetism; akustik; optik; Elektromagnetism; optics; acoustics; Photon echo; Quantum optics; Quantum computing; Fysicumarkivet A:2003:Ohlsson;

    Abstract : In this thesis, aspects of the use of cryogenically cooled rare-earth-ion-doped crystals in the fields of quantum optics and quantum information processing are addressed. The experiments and theoretical considerations referred to in this thesis are based on the coherent transient interaction between light and the ions in the crystals. READ MORE

  6. 4. Phase-Contrast and High-Resolution Optics for X-Ray Microscopy

    Author : Olof von Hofsten; Ulrich Vogt; Ian McNulty; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; Microscopy; X-ray optics; X-ray microscopy; Soft X-ray physics; Optics; Optik; Physics; Fysik;

    Abstract : X-ray microscopy is a well-established technique for nanoscale imaging. Zone plates are used as microscope objectives and provide high resolution, approaching 10 nm, currently limited by fabrication issues. This Thesis presents zone plate optics that achieve either high resolution or phase contrast in x-ray microscopy. READ MORE

  7. 5. Laboratory soft x-ray microscopy and tomography

    Author : Michael Bertilson; Hans Hertz; Gerd Schneider; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; Microscopy; X-ray optics; Diffractive optics; Zone plates; X-ray microscopy; Soft X-ray physics; Tomography; Optics; Optik; Physics; Fysik;

    Abstract : Soft x-ray microscopy in the water-window (λ = 2.28 nm – 4.36 nm) is based on zone-plate optics and allows high-resolution imaging of, e.g. READ MORE
