  1. 6. Photonic devices with MQW active material and waveguide gratings : modelling and characterisation

    Författare :Nadeem Akram; Lars Thylén; Hartmut Hillmer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Method of Lines; Grating; ARROW Waveguide; Semiconductor laser; quantum well; Photonics; Fotonik;

    Sammanfattning : The research work presented in this thesis deals with modelling, design and characterisation of passive and active optical waveguide devices. The rst part of the thesis is related to algorithm development and numerical modelling of planar optical waveguides and gratings using the Method of Lines (MoL). LÄS MER

  3. 7. Design, Fabrication, and Characterization of Nano-Photonic Components Based on Silicon and Plasmonic Material

    Författare :Liu Liu; Lars Thylén; Roe Baets; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nano-photonics; finite-difference time-domain method; finite-difference mode solver; amorphous silicon; silicon nanowire; arrayed waveguide grating; photonic crystal; Photonics; Fotonik;

    Sammanfattning : Size reduction is a key issue in the development of contemporary integrated photonics. This thesis is mainly devoted to study some integrated photonic components in sub-wavelength or nanometric scales, both theoretically and experimentally. LÄS MER

  4. 8. Entanglement in quantum communication : preparation and characterization of photonic qubits

    Författare :Daniel Ljunggren; Gunnar Björk; Hugo Zbinden; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photonics; Fotonik;

    Sammanfattning : At the heart of quantum physics lies the principle of superposition, and at the heart of information theory lies the bit. Perhaps the most useful property of quantum systems is that they can be loaded with information bits, so-called qubits, that are indefinitely both 0 and 1 until a measurement is made. LÄS MER
