The title of Aisling's thesis is "Optical Pulse Processing Towards Tb/s High-Speed Photonic Systems".
She completed her PhD in the Radio & Optical Communications Laboratory at the Research Institute for Networks and Communications Engineering (RINCE) and the School of Electronic Engineering, DCU under the supervision of Professor Liam Barry.
Brief description of Project:
Due to the continued growth of high-bandwidth services
provided by the internet, there is a requirement
This project was generously funded by Science Foundation Ireland (SFI) and Enterprise Ireland.

Congratulations
to Aisling Clarke who successfully defended her thesis and will be awarded the
degree of PhD.
to
operate individual line rates in excess of 100 Gb/s in next-generation
optical communications systems. In order to implement these high-speed
networks, processing of information is required to be carried out optically
as electronic processing capability is presently limited to 40 Gb/s. This
project focussed on two important sub-systems of an optical communications
network, transmitter and wavelength converter. A high-quality pulse source
suitable for 80 Gb/s systems was developed and optical techniques were
investigated to enhance the quality of the generated pulses (components used
include a fibre Bragg grating and saturable absorber). In addition an 80 Gb/s
wavelength converter was achieved by exploiting nonlinearities in a
semiconductor optical amplifier in conjunction
