  2. 21. All-Optical Switching with the Nonlinear Optical Loop Mirror

    Author : Bengt-Erik Olsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis deals with the theory and applications of the nonlinear optical loop mirror (NOLM). Novel methods to restore and filter optical data as well as generate high peak power optical pulses using the NOLM are demonstrated. READ MORE

  4. 22. Optical characterization of potential drugs and drug delivery systems

    Author : Erik Rosenbaum; Lennart B-Å Johansson; Sven Engström; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pilicide; Ganglioside GM1 micelles; Drug Delivery; Elecronic Energy Transfer; UV-Vis Absorption; Fluorescence Spectroscopy; Biophysical chemistry; Biofysikalisk kemi; fysikalisk kemi; Physical Chemistry;

    Abstract : This Thesis is a characterization study on substances having potency as drugs as well as on a lipid based drug-delivery matrix. The optical properties of newly synthesized molecules with proven pilicide properties have been characterized with several spectroscopic methods. READ MORE

  5. 23. Laser cooling mechanisms and Brownian motors in optical lattices

    Author : Peder Sjölund; Anders Kastberg; Svante Jonsell; Chris Westbrook; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Optical physics; Optisk fysik;

    Abstract : Denna avhandling innefattar såväl experimentella som numeriska studier av laserkylda atomer i optiska kristallgitter. Bland annat har laserkylningsprocesser studerats, där atomers rörelser i optiska kristallgitter har uppvisat andra typer av bakomliggande mekanismer än de som tidigare förutsågs genom “Sisyfoskylningsmodellen”.

  6. 24. Material and technique development for ultrasound optical tomography using spectral hole burning filters

    Author : Alexander Bengtsson; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biomedical imaging; ultrasound optical tomography; acousto-optical tomography; rare-earth-ion doped crystals; spectral holeburning; slow light filters; Tm 3:LaF3; Fysicumarkivet A:2022:Bengtsson;

    Abstract : The molecular sensitivity provided by optical photons has potential advantages in medical diagnostics, for example, in distinguishing healthy from cancerous tissue. However, scattering resulting from inhomogeneities in the refractive index of tissues prevents spatially resolved optical measurements in biological material, except at very shallow depths.

  7. 25. Electron tomography and optical modelling for organic solar cells

    Author : Viktor Andersson; Olle Inganäs; Joachim Loos; Linköpings universitet; []
    Keywords : Organic solar cells; Electron tomography; Optical modelling;

    Abstract : Organic solar cells using carbon based materials have the potential to deliver cheap solar electricity. The aim is to be able to produce solar cells with common printing techniques on flexible substrates, and as organic materials can be made soluble in various solvents, they are well adapted to such techniques.
