Hybrid Optoelectronics

US logoThe Southampton node brings to the Network its expertise in the optical spectroscopy of semiconductor nanostructures and a variety of fabrication methods of novel nanoscale structures. The group possesses large experimental infra-structure with four fully equipped laboratories for optical spectroscopy and characterisation of semiconductor devices. Relevant to the proposal, these include high spatial/spectral resolution set-ups for low temperature spectroscopy (including magneto-spectroscopy), equipped with both continuous wave picosecond and femtosecond tuneable wavelength lasers, and ultra-sensitive detectors of both optical and electrical signals including a streak camera with 2ps resolution. In addition, the group strongly benefits from the recent investment of the University of Southampton, Merck and the Research Council of UK in extended nano-prototyping cleanroom facilities worth more than £30m.

Available Resources

Southampton University, as a pioneer of optical fibre technology, is equipped with a wide range of advanced fabrication and characterisation equipment, installed over several closely collaborating institutes.

Flagship of the university, the Southampton Nanofabrication Centre is one of the premiere cleanrooms in Europe and houses a wide array of state of-the-art microfabrication, nanofabrication and characterisation tools. The Centre has a uniquely broad range of technologies, combining traditional and novel top down fabrication with state-of-the-art bottom up fabrication. This allows us to develop and produce a wide range of devices in diverse fields such as electronics, nanotechnology and bionanotechnology and incorporate them into an equally comprehensive array of nano and microsystems for analysis and use. The characterisation capability is similarly extensive catalogue of microscopes and test gear, from nanometre resolution scanning microscopes to electrical, magnetic and RF analysis.

Additional optical characterisation facilities are available in the nearby Optoelectronics Research Center and in the Department of Physics and Astronomy. Ultra-fast spectroscopy equipment can be used to characterize the photoluminescence dynamics of semiconductors, with a variety of femtosecond to picosecond lasers and detectors. Full LED (angle resolved emission, PLQY, etc…) and PV (EQE, IQE, PCE) characterization facilities are also available.

Key Personnel

Prof Pavlos Lagoudakis at the School of Physics and Astronomy has experience in the optical spectroscopy of semiconductor quantum dots, organic semiconductors, epitaxial heterostructures and hybrid configurations of the above. He received a bachelor of science in Physics in 2000 from the National University of Athens, Greece. In 2003 he was awarded his PhD in experimental physics from the University of Southampton, UK. Following his PhD, he moved to the University of Munich, as a postdoctoral researcher. In 2006, Pavlos was awarded an Academic Fellowship from the Research Council of UK and re-joined the University of Southampton. Since he moved to Southampton he has formed a new group, and built the Laboratories for Hybrid Optoelectronics (four laboratories dedicated to spectroscopy). In 2008 Lagoudakis was appointed to the chair of nanoscience at the School of Physics and Astronomy. The Southampton team will also include strong input from Prof Richard Harley, a senior member of the school has pioneered in the field of semiconductor spectroscopy with the first investigations of Kerr rotation in ultrafast pump-probe configuration on two dimensional electron gases and of optical nuclear magnetic resonance in semiconductor heterostructures. He has published over 100 refereed papers and has given many invited talks on the topic at international and national conferences.
