• Regrowth-free monolithic vertical integration of passive and active waveguides 

  Duggan, Shane P. (University College Cork, 2019)

  Data usage continues to rise exponentially with user demand, and the bandwidth of optical communications is reaching its limit. Spectrally efficient advanced modulation formats are being used to increase the data rate ...
• Dynamically reconfigurable long-reach PONs for high capacity access 

  Carey, Daniel (University College Cork, 2019)

  Fibre-to-the-Premises (FTTP) is currently seen as the ultimate in high-speed transmission technologies for delivering ubiquitous bandwidth to customers. However, as the deployment of network infrastructure requires a ...
• Design and fabrication of single-mode tunable lasers for regrowth-free monolithically integrated photonic circuits 

  Caro, Ludovic (University College Cork, 2019)

  In this communication age, the bandwidth requirements are increasing exponentially with the development of more and more data-intensive services, from high-definition video streaming and cloud-based computing to the Internet ...
• Site-controlled quantum dots as sources of quantum light 

  Moroni, Stefano T. (University College Cork, 2018)

  Quantum information is at its infancy. Though several different approaches are being pursued, the ability of manipulating a quantum state and make two quantum systems interact in a controlled way is still a great challenge, ...
• Theory and optimisation of metamorphic photonic devices 

  Bogusevschi, Silviu (University College Cork, 2018)

  Metamorphic growth of semiconductor materials – in which a “virtual” substrate with a desired lattice constant is obtained by growing a lattice-mismatched metamorphic buffer layer (MBL) on a conventional substrate such as ...
