• Mutually coupled lasers on a photonic integrated circuit 

  Perrott, Alison H. (University College Cork, 2020-10)

  The number of internet users and the internet traffic are growing exponentially year-on-year, leading to an ever-increasing demand for data. This demand risks saturating the current network and is, therefore, driving ...
• Tb/s superchannels for optical communications 

  Kaur, Amandeep (University College Cork, 2020-09-01)

  The exponential growth of data traffic has motivated the researchers to find the transmission technologies which can offer high capacity transmission with high spectral efficiency (SE) at economical cost. The next-generation ...
• Electronic excitation and atomic forces in optically excited group V semimetals 

  O'Mahony, Shane M. (University College Cork, 2020-09-02)

  The main focus of this work is to investigate how electronic excitation changes the forces between atoms in materials, causing large amplitude collective atomic motion, referred to as coherent phonon motion. The recent ...
• Quantum control of many-particle systems via shortcuts to adiabaticity 

  Dowdall, Tom (University College Cork, 2020-06-19)

  A major barrier for the development of new quantum technologies is fast and robust methods for preparing and manipulating complex quantum states. To date preparation and manipulation of quantum systems has primarily been ...
• 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 ...
