- Gian-Luca Oppo
- Chair of Computational Physics supported by SGI
- Department of Physics and A.P.
- University of Strathclyde, Glasgow
Special thanks to Dr. A. J. Scroggie
2Opto-electronics
- Integration of optical and electronic
technologies - It employs light to process and transfer data
(e.g. lasers) - Main applications communications (more than 70
of terrestrial phone lines in the UK are
optical), CD-DVD players, sensors, components,
technology for medicine etc. - Present market world-wide over 100 billions U
- Present status on the stock market HEALTHY in
spite of recent downturns
3Optoelectronics in Scotland
- Employs more than 5000 people at present
- Steady and fast growth. Turnover over 600 million
- Well established companies (Marconi, BAE,
Pilkington, Agilent, etc.) as well as a large
number of new and innovative companies of recent
years (Kymata, Coherent Scotland, Intense
Photonics, Kamelian, Optos ..) - Many spin-offs from Scottish Univeristies
- Great industry-academia partnerships
- Major support from Scottish Enterprise

10Example 2Virtual Laser Laboratory
11Example 3 Handling Complex Data in a Virtual
Environment
- Optical detection
- Removal of noise (filtering)
- Data decoding reconstruction
- High dimensional correlations
- Comparison with data from virtual models
prototypes - Three, four higher dimensional renderings
- Data coding and long distance transmission
12Example 4 Virtual Application of OE.Trapping
Atoms in Optical Sprinklers
- New shape of a Laser output intensity
- Central hole and narrow dark line
- Fast rotation in time
- Possibility of trapping atoms in the beam centre
- Slow atoms remain trapped while fast ones leave
the beam
