  1. 1. Optical Transmission Systems Based on Phase-Sensitive Amplifiers

    Author : Samuel L I Olsson; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical injection locking; fiber nonlinearities; optical fiber communication; fiber nonlinearity mitigation; four-wave mixing; fiber optic parametric amplification; low-noise amplification; phase-sensitive amplification; fibre optics;

    Abstract : The capacity and reach of today's long-haul fiber optical communication systems is limited by amplifier noise and fiber nonlinearities. Conventional, phase-insensitiveamplifiers (PIAs), have a quantum limited noise figure (NF) of 3 dB at high gain, meaning that with a shot-noise limited input signal the signal-to-noise ratio (SNR)is degraded by at least 3 dB.

  2. 2. Gas phase molecular relaxation probed by synchrotron radiation experiments

    University dissertation from Stockholm : Fysik

    Author : Jaume Rius i Riu; KTH.; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Molecular relaxation; synchrotron radiation; dispersed fluorescence; photoelectron spectroscopy; energy resolved electron ion coincidence technique;

    Abstract : This thesis presents experimental studies of gas phasemolecular relaxation after excitation with synchrotron photonsin the 15-35 eV and in the 70-350 eV regions.In the 15-35 eV region, molecular relaxation by neutraldissociation processes and nonFranck-Condon effects in N2 and O2 molecules have beenstudied by means of dispersed fluorescence and photoelectronspectroscopy experimental techniques, respectively.

  3. 3. Phase Diagrams, Microstructure and Phase Separation in Alkyl Glucoside Systems

    University dissertation from Johan Reimer, Chemical Centre, Lund University

    Author : Johan Reimer; Lund University.; Lunds universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Physical chemistry; micellar network; NMR diffusometry; microemulsion; microstructure; phase diagram; phase separation; phase behaviour; alkyl glucoside; sugar surfactant;

    Abstract : The aim of this thesis work was to study phase diagrams, microstructure and phase separation in alkylglucoside systems. Both alkyl glucoside/water systems and microemulsions with alkyl glucosides have been studied. READ MORE

  4. 4. Thermally and Optically Excited Electron Transport in Semiconductor Nanowires

    University dissertation from Division of Solid State Physics, Lund University, Box 118, SE-221 00 Lund, Sweden

    Author : I-Ju Chen; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2018]

    Abstract : This thesis explores the transport of thermally and optically excited electrons invarious nanowire structures. On one hand, electrons are thermally excited when thetemperature is nonzero, and the thermal energy help them surmount energy barriersthat are present in the material. READ MORE

    Abstract : A new kind of lipid/polymer composite particle, consisting of a biodegradable polymer matrix with well-defined lipid domains, has been created. The lipid used is the water-swelling lipid monoolein (MO), which forms a reversed bicontinuous cubic diamond structure in aqueous solutions. READ MORE
