• Evolution of the magnetic field structure in the jet outflows from active galaxies 

  Knuettel, Sebastian (University College Cork, 2020-05)

  This thesis concerns studies into the magnetic fields in the jets from active galactic nuclei (AGN). Helical and toroidal magnetic fields are expected to exist in AGN jets close to the jet base and to assist in the launching ...
• Optical comb injection for optical demultiplexing and harmonic frequency locking 

  Shortiss, Kevin (University College Cork, 2020-04-17)

  With the continued growth of internet traffic, new optical communication infrastructures capable of dramatically increasing network bandwidth are being considered. Optical superchannels consisting of densely packed channels ...
• Laser-induced plasmas in air for pulsed broadband cavity-enhanced absorption spectroscopy 

  Keary, Bryan P. (2020-01-07)

  A pulsed laser-induced plasma (LIP) was generated in ambient air inside a high-finesse near-concentric optical cavity. The broadband optical plasma emission was successfully sustained within the cavity and the light leaking ...
• Dense wavelength division multiplexing at 2 μm for future optical communications 

  Kavanagh, Niamh (University College Cork, 2019)

  The internet is ubiquitous in our lives today, enabling instantaneous access to information, increased international collaboration, and even real-time remote surgery. It has changed how we socialise and how we see the ...
• MOVPE metamorphic lasers and nanostructures engineering at telecom wavelengths 

  Mura, Enrica (University College Cork, 2019)

  In recent years, considerable attention has been drawn to the design of heterostructures on GaAs substrates emitting in the 1.3-µm spectral range for replacing InP injection lasers in medium range fiber-optic communication ...
