Title: Virtual Optoelectronics with SGI at Strathclyde


1
Virtual Opto-electronics with SGI at Strathclyde
  • 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

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

Virtual Optoelectronics at Strathclyde
  • Cheap assessment of devices ahead of
    fabrication
  • The VIDEOS and VISION Projects
  • Example 1 Virtual devices
  • Example 2 Virtual laser laboratory
  • Example 3 Handling optical data in a virtual
    environment
  • Example 4 A virtual application trapping atoms
    in optical sprinklers

5
SGI Facilities for VOE at Strathclyde
  • 12 parallel processors ONYX 2 (small) Virtual
    Reality T.
  • 16 parallel processors Origin 300 (just
    installed)
  • Three 4 processors Origin 200 14 SGI
    workstations
  • New VIDEOS award ?

The VIDEOS Project
  • Virtual Interactive Design of Electronics and
    Opto-electronics Systems (2 parallel
    supercomputers)
  • Collaboration with EEE at Glasgow University
  • Supported by SHEFC RDG grant

Example 1 Virtual Devices
  • Numerical simulations of Laser systems and other
    Opto-electronics devices
  • High level of accuracy of numerical models
  • Parallel implementation on HPC machines
  • Possible reliable comparison with experiments
  • Virtual Prototypes

Example 2Virtual Laser Laboratories
Interactive Projects
  • Research Project Dilemma

Theory Too difficult ! Experiments Too
expensive ! SOLUTION Virtual Laboratories
Absorber

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

12
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

Conclusions
  • Virtual Optoelectronics with High Performance
    Computing is a reality
  • Powerful combination of graphics and numerical
    simulations
  • Applications in Research and Industrial RD
  • Preparation of future generation of skilful
    employees
  • Thanks to J Cowen, I Wallace and S Wilson
