  1. 6. Technology and properties of InP-based photonic crystal structures and devices

    Författare :Naeem Shahid; Srinivasan Anand; Rob W. vad der Heijden; KTH; []
    Nyckelord :Integrated optics materials; Photonic crystals; Planar waveguides; Dispersion; Band-gap; Mode-gap; mini-stopband; InP; Nanostructure fabrication; dry etching; mass transport; material reflow; reliability; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : Photonic crystals (PhCs) are periodic dielectric structures that exhibit a photonic band gap; a range of wavelengths for which light propagation is forbidden. 2D PhCs exhibit most of the properties as their three dimension counterparts with a compatibility with standard semiconductor processing techniques such as epitaxial growth, electron beam lithography, Plasma deposition/etching and electromechanical lapping/polishing.

    Sammanfattning : Semiconductor nanowire solar cells have achieved comparable efficiency to their planar counterparts with substantial reduction of material consumption. Tandem geometry is a path towards even higher efficiency. However, extensive studies are needed to reach this goal. LÄS MER

  7. 10. Design, Fabrication and Analysis of InP-InGaAsP Traveling-Wave Electro-Absorption Modulators

    Författare :Stefan Irmscher; KTH; []
    Nyckelord :fiber-optic communication; modulator; electroabsorption; traveling-wave; InP; broad-band modulation;

    Sammanfattning : External modulators will become key components in fiberoptical communica- tion systems operating at 40Gbit/s andhigher bitrates. Semiconductor electro- absorption (EA)modulators are promising candidates because of their high-speed potential, and their process compatibility with thecorresponding semi- conductor laser light sources.
