  • Chang, Tongwei; Mathewson, Alan; Kennedy, Michael Peter; Greer, James C. (IEEE, 2004-11)
    A modification to heterodimensional field effect transistors (HDFET) is introduced and demonstrated to provide novel switching capabilities. The modification consists of introducing a split drain into the HDFET structure ...
  • Dailey, James M.; Koch, Thomas L. (IEEE, 2007)
    Complex-valued time-resolved transmission characteristics of a semiconductor optical amplifier (SOA) are measured using a spectrogram technique.  A relatively simple traveling-wave density matrix model is implemented that ...
  • Dailey, James M.; Koch, Thomas L. (IEEE, 2009-04-24)
    We present an analysis of semiconductor optical amplifier (SOA) based differential Mach-Zehnder wavelength converters with a specific focus on optimizing performance through intentional asymmetries in optical power splitting, ...
  • Dailey, James M.; Ibrahim, Selwan K.; Manning, Robert J.; Webb, Rod P.; Lardenois, Sébastien; Maxwell, Graeme D.; Poustie, Alistair J. (Institution of Engineering and Technology, 2009-09)
    We demonstrate an SOA-based all-optical high-speed Mach-Zehnder interferometer exclusive- OR (XOR) gate fabricated in a silica III-V hybrid-integration technology platform.  The device includes integrated time delays for ...
  • Seifikar, Masoud (University College Cork, 2013)
    The substitution of a small fraction x of nitrogen atoms, for the group V elements in conventional III-V semiconductors such as GaAs and GaSb strongly perturbs the conduction band of the host semiconductor. In this thesis ...
  • Caro Bayo, Miguel Ángel (University College Cork, 2013)
    In this work, the properties of strained tetrahedrally bonded materials are explored theoretically, with special focus on group-III nitrides. In order to do so, a multiscale approach is taken: accurate quantitative ...
  • Cleary, Ciaran Sean (University College Cork, 2013)
    Electronic signal processing systems currently employed at core internet routers require huge amounts of power to operate and they may be unable to continue to satisfy consumer demand for more bandwidth without an inordinate ...
  • Sheehan, Robert Noel (University College Cork, 2013)
    A model for understanding the formation and propagation of modes in curved optical waveguides is developed. A numerical method for the calculation of curved waveguide mode profiles and propagation constants in two dimensional ...
  • Razavi, Pedram (University College Cork, 2013)
    In this work by employing numerical three-dimensional simulations we study the electrical performance and short channel behavior of several multi-gate transistors based on advanced SOI technology. These include FinFETs, ...
  • Gity, Farzan (University College Cork, 2013)
    Silicon (Si) is the base material for electronic technologies and is emerging as a very attractive platform for photonic integrated circuits (PICs). PICs allow optical systems to be made more compact with higher performance ...
