UCC’s Research Highlights Lecture Series will continue with the next lecture on Thursday next, February 19th when Professor Eoin O’Reilly will discuss semiconductor quantum dots for controlled light sources.
Photonics describes systems that operate not just by moving electrons about but also by manipulating light. Semiconductor optical sources are among the key photonic components underpinning a wide range of technologies from high-bandwidth telecommunications to bio-medicine. Nevertheless, to make photonics as pervasive as electronics, we need breakthroughs in the physics of advanced materials.
Of particular interest are semiconductor quantum dots, which are of sufficiently small dimensions that quantum effects dominate, and the dots behave like artificial atoms which can be readily addressed by driving an electrical current through the surrounding semiconductor material. The development of quantum dots, explained Professor O’Reilly, to their present level has required close and successful interaction across a range of disciplines, including physics, materials science and engineering, and has benefited strongly from close interaction between experimental developments and theoretical analysis.
Tyndall and UCC researchers, supported by the Programme for Research in Third Level (PRTLI), have played a key role in all of these developments. This talk describes how the controlled growth, analysis and engineering of semiconductor quantum dots is now enabling a new generation of optical sources, with wide potential across a range of applications, including high-speed communications, quantum cryptography and information processing, and biophotonics.
Eoin O’Reilly is the Head of the Theory, Modelling and Design Centre and of the Photonics Theory Group at the Tyndall National Institute/Physics Department, UCC.
To celebrate 10 years of PRTLI investment in UCC, and to mark its contribution to the development of the University, the region and the nation, the UCC Research Highlights Lecture Series aims to convey to a wide audience the significance and impact of PRTLI investment in UCC.
The Lecture Series will continue until May 7th 2009 and cover a wide range of topics including nanoscience and technology; food & health; cell biology; environment, marine and energy.
The lecture will take place on Thursday, February 19th at 1.00pm in the Aula Maxima, UCC. Admission is free, and as always, members of the public are invited to attend.
