  2. 1. Photoemission Electron Microscopy for Ultrafast Nano-Optics - Femtoseconds to Attoseconds

    Author : Erik Mårsell; Synkrotronljusfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nanorice; Spatiotemporal imaging; Attosecond pulses; Fysicumarkivet A:2016:Mårsell; Nanowires; Silver nanostructures; Femtosecond laser pulses; PEEM; Plasmonics; Ultrafast nano-optics;

    Abstract : Ultrafast nano-optics is a new and quickly evolving research field centred around the control, manipulation, and application of light on a nanometre and femtosecond scale. This can lead to improved electro-optical devices, more sensitive spectroscopy, and real-time control of chemical reactions. READ MORE

  4. 2. Designer magnetoplasmonics for adaptive nano-optics

    Author : Irina Zubritskaya; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Photonics; magnetoplasmonics; magneto-optics; magneto-optical Kerr effect MOKE ; plasmon ruler; nickel; cobalt; gold; silicon; localized surface plasmon resonance; dimer; trimer; chiroptics; chiral transmission; 2D nanoantennas; dynamic tuning; metal-dielectric; 3D nanoantennas; metasurface; magnetic modulation; perpendicular magnetic anisotropy.;

    Abstract : Materials that provide real-time control of the fundamental properties of light at visible and near-infrared frequencies enable the essential components for future optical devices. Metal nanostructures that couple electromagnetic (EM) radiation on a sub-wavelength length scale to free electrons, forming propagating or localized surface plasmons, provide many exciting functionalities due to their ability to manipulate light via the local EM field shaping and enhancement.

  5. 3. Momentum exchange between light and nanostructured matter

    Author : Daniel Andrén; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase-gradient metasurface; optical force and torque; metavehicle; momentum exchange.; nano-optics; rotary nanomotor; optical tweezers;

    Abstract : An object's translational and rotational motion is associated with linear and angular momenta. When multiple objects interact the exchange of momentum dictates the new system's motion. READ MORE

  6. 4. Optical Studies of Single Quantum Dots

    Author : Jonas Persson; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nano-optics; quantum optics; photoluminescence; micro-photoluminescence; single photon generation; Semiconductory physics; Halvledarfysik; low-dimensional structures; quantum dots; Stranski-Krastanow; Fysicumarkivet A:2004:Persson;

    Abstract : This thesis presents spectroscopic studies of single self-assembled InP quantum dots (QDs). The electronic properties of these QDs have been studied by photoluminescence (PL) and scanning tunnelling luminescence (STL). The QDs were grown in the Stranski-Krastanow mode and were embedded in GaInP. READ MORE

  7. 5. Optical Studies and Applications of Single Quantum Dots

    Author : Valéry Zwiller; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; time resolved photoluminescence; Physics; Fysik; Semiconductory physics; Halvledarfysik; Condensed matter:electronic structure; electrical; magnetic and optical properties; supraconductors; magnetic resonance; relaxation; spectroscopy; Kondenserade materiens egenskaper:elektronstruktur; egenskaper elektriska; magnetiska och optiska ; supraledare; spektroskopi; magnetisk resonans; microphotoluminescence; microcavities; photoluminescence; quantum optics; nano-optics; photonics; low dimensional structures; quantum dots; Fysicumarkivet A:2001:Zwiller;

    Abstract : The luminescence from single quantum dots has been studied. Single dot photoluminescence was studied under continuous as well as under pulsed excitation. Time-resolved studies revealed fast relaxations in quantum dots. The time resolved measurements were fitted with a set of rate equations. READ MORE
