  4. 2. Ion beam etching of InP based materials

    Author : Carl-Fredrik Carlström; KTH; []
    Keywords : InP; dry etching; ion beam etching; RIBE; CAIBE; hydrocarbon chemistry; trimethylamine; As P exchange reaction; morphology; low damage; AFM; SCM; annealing;

    Abstract : Dry etching is an important technique for pattern transferin fabrication of most opto-electronic devices, since it canprovide good control of both structure size and shape even on asub-micron scale. Unfortunately, this process step may causedamage to the material which is detrimental to deviceperformance. READ MORE

  5. 3. Top-down Fabrication Technologies for High Quality III-V Nanostructures

    Author : Shagufta Naureen; Srinivasan Anand; Clivia M. Sotomayor Torres; KTH; []

    Abstract : Photonic crystals (PhCs) are structures periodic in thedielectric constant. They exhibit a photonic bandgap, i.e., arange of wavelengths for which light propagation is forbidden. READ MORE

  7. 5. Technology and properties of InP-based photonic crystal structures and devices

    Author : Naeem Shahid; Srinivasan Anand; Rob W. vad der Heijden; KTH; []
    Keywords : 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;

    Abstract : 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.
