    Abstract : Structuring of semiconductor materials is utilized in many optoelectronic devices, e.g, in order to make them more efficient, cost-effective, and/or to obtain specific wavelength-engineered responses. Semiconductor materials are widely used in optoelectronic devices due to their favorable optical and electric properties. READ MORE

  3. 3. Advances in Holographic Optical Trapping

    Author : Martin Persson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : Optical tweezers; Holographic optical trapping; Optical force measurement; Spatial light modulators; Holographic beam steering; Liquid crystals;

    Abstract : Holographic optical trapping (HOT) is a technique for non-invasive dynamic anipulation of multiple microscopic objects, which has been used for many applications in the life sciences during the past decade. The technique uses holographic beam steering with a spatial light modulator (SLM) to direct light to the desired positions of optical traps. READ MORE

  4. 4. Optical Levitation of Charged Droplets

    Author : Oscar Isaksson; Chalmers University of Technology; []
    Keywords : water; Optical manipulation; neutralization; Radiation Pressure; demonstration; Millikan Oil Drop experiment; evaporation;

    Abstract : The development of an experimental system used to investigate charged droplets is presented. The experimental setup combines optical levitation with Millikan's classical oil drop experiment and has also been used as a mean to demonstrate fundamental physical phenomena. READ MORE

  5. 5. Lab on a chip for electrophysiological measurements with control of the oxygen content : optical manipulation and spectroscopic analysis of biological cells

    Author : Ahmed Alrifaiy; Luleå tekniska universitet; []
