  • Dailey, James M.; Webb, Rod P.; Manning, Robert J. (Optical Society of America, 2010-07-25)
    We numerically investigate a novel 40 Gbps OOK to AMI all-optical modulation format converter employing an SOA-based Mach-Zehnder interferometer.  We demonstrate operation with a 27-1 PRBS and explain the phase modulation's ...
  • Dailey, James M.; Webb, Rod P.; Manning, Robert J. (Optical Society of America, 2011-12-12)
    We describe a novel SOA-based all-optical pure-phase modulator, and show how deleterious cross-gain modulation from the SOAs can be suppressed by utilizing an integrated interferometer structure. We experimentally demonstrate ...
  • 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 ...
