  2. 6. Silicon Based Photonic Devices and Their Applications

    Author : Qiang Li; Min Qiu; Geert Morthier; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Optics; Optik;

    Abstract : The integration of modern electronic devices for information processing is rapidly ap-proaching an interconnect bottleneck. Silicon photonics can be a promising solution forcircumventing this bottleneck, as already being anticipated by many electronics manu-facturers including HP, IBM and Intel. READ MORE

  5. 8. Near-Field Radiative Heat Transfer between Plasmonic Nanostructures

    Author : Jin Dai; Min Yan; Philippe Ben-Abdallah; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fysik; Physics; Energy Technology; Energiteknik;

    Abstract : Radiative heat transfer (RHT) due to coupled electromagnetic near field scan significantly exceed that dictated by Planck’s law. Understanding such phenomenon is not only of fundamental scientific interest, but also relevant to a broad range of applications especially connected to nanotechnologies. READ MORE

  6. 9. Structural Information Content of the Optical Field

    Author : Per Martinsson; Ari Friberg; Karl-Heinz Brenner; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photonics; Fotonik;

    Abstract :  The communication modes are a mathematical technique for the description of structural information in optical fields. These modes are orthogonal, optimally  connected functions characteristic of the optical system. Mathematically they are obtained by the singular value decomposition (SVD) of the operator that represents the field propagation. READ MORE

  7. 10. Photothermal Effect in Plasmonic Nanostructures and its Applications

    Author : Xi Chen; Min Qiu; Sergey I. Bozhevolnyi; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plasmonic; Photothermal Effect; Silicon Photonics; Gold Nanoparticles; Physics; Fysik;

    Abstract :   Plasmonic resonances are characterized by enhanced optical near field and subwavelength power confinement. Light is not only scattered but also simultaneously absorbed in the metal nanostructures. READ MORE
