  1. 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

  2. 2. Adaptive Optics in Integrated Modeling of Telescopes

    Author : Anita Enmark; Astronomi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; extremely large telescope; adaptive optics; Integrated model;

    Abstract : This thesis present the implementation of a modular adaptive optics (AO) model, as part of an integrated model of extremely large telescopes (ELTs). The purpose of the project has been to establish knowledge within integrated modeling, with emphasis on adaptive optics. READ MORE

  3. 3. Integrated Nonlinear Optics in Silicon Nitride Waveguides

    Author : Clemens Krückel; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; integrated optics devices; nonlinear optics materials; four-wave mixing; nonlinear optical signal processing; wavelength conversion devices; nanostructure fabrication;

    Abstract : Current nanofabrication techniques allow patterning of optical waveguides with submicron cores. This results in strong confinement of light, which leads to high optical intensities. READ MORE

  4. 4. Multiparty Quantum Communication and fs-laser Written Integrated Optics Circuits

    Author : Ashraf Mohamed El Hassan; Mohamed Bourennane; Guillermo Andler; Marcos Curty; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Quantum optics; quantum communication; quantum cryptography; fs-laser written waveguides; integrated optics circuits; Physics; fysik;

    Abstract : Quantum information science, the rapidly developing interdisciplinary field,  gives power to the information and communications technologies (ICT) by  providing secure communication, precision measurements, ultra-powerful simulation and ultimately computation. It is well known that photons are an ideal candidate for encoding the quantum bit, or "qubit", in quantum information and specially for quantum communication. READ MORE

  5. 5. Integrated Nanophotonic Devices in Lithium Niobate

    Author : Mohammad Amin Baghban; Katia Gallo; Fabrice Raineri; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Lithium niobate LN ; LN-on-insulator; photonic integrated circuits; nonlinear optics; electro-optics; waveguides; propagation losses; Bragg gratings; grating couplers; polarization-insensitive; LN for life sciences; Physics; Fysik;

    Abstract : Lithium niobate (LN) is a ferroelectric crystal offering a broad transparency spectrum, together with excellent electro-optic and nonlinear optical properties. Thanks to them, LN is setting the standard for quantum optics and telecommunications in critical applications such as ultrafast modulation and frequency conversion. READ MORE
