  2. 11. 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

  6. 14. Epitaxial III-V/Si heterojunctions for photonic devices

    Author : Giriprasanth Omanakuttan; Sebastian Lourdudoss; Yanting Sun; Harri Lipsanen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; epitaxy; heterojunction; III-V on Si integration; solar cell; Fysik; Physics;

    Abstract : Monolithic integration of III-V materials on silicon is of great interest for efficient electronic-photonic integrated devices and multijunction solar cells on silicon. However, defect formation in the heteroepitaxial layers due to lattice mismatch, thermal mismatch, and polarity mismatch makes it a great challenge. READ MORE

  7. 15. Technology for photonic components in silica/silicon material structure

    Author : Lech Wosinski; KTH; []
    Keywords : silica-on-silicon technology; PECVD; plasma deposition; photonic integrated circuits; planar waveguide devices; UV Bragg gratings; photosensitivity; arrayed waveguide gratings; multimode interference couplers; add-drop multiplexers;

    Abstract : The main objectives of this thesis were to develop a lowtemperature PECVD process suitable for optoelectronicintegration, and to optimize silica glass composition forUV-induced modifications of a refractive index in PECVDfabricated planar devices. The most important achievement isthe successful development of a low temperature silicadeposition, which for the first time makes it is possible tofabricate good quality low loss integrated components whilekeeping the temperature below 250oC during the entirefabrication process.
