Opto-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

Optoelectronics 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

Example 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

Example 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
