David R. Selviah studied Physics and Theoretical Physics at Trinity College, Cambridge University specializing in mathematical modelling. After internships at the Royal Aircraft Establishment, Texas Instruments-Geophysical Service International, and CERN, Geneva he joined the industrial electronics company Plessey (now Bookham Technology) at their main research laboratories in Caswell where he designed, modelled, clean room fabricated and characterised novel RF surface acoustic wave correlators for use in pulsed radar and secure communications.

In 1983 he joined the Department of Engineering Science and Christchurch, Oxford University to design, model, clean room fabricate and characterise SAW RF linear chirp pulse compression filters for use in radar systems and oversaw the transfer of the technology to a manufacturing company. In 1987 he joined the Department of Electronic and Electrical Engineering, UCL where he founded the Optical Devices and Systems Research Laboratory and carried out research for 20 years leading to over 100 publications and patents. David is academic leader of the £1.3 million EPSRC IeMRC Flagship project on Optical waveguide Printed Circuit Boards (OPCBs) in which 3 universities and 10 companies are collaborating.

Dr Selviah's reseach group "Optical Devices and Systems Laboratory" is recognised as delivering world leading research and is listed as a UK Technology Centre of Excellence

Research interests include:

  • Design rules and fabrication techniques for low cost, optical polymer waveguides integrated into optical printed circuit boards, OPCBs
  • low cost, active, 4-channel, duplex, 10 Gb/s per channel, connectors incorporating self alignment, 4 VCSEL 850 nm optical sources with drivers, 4 photodiode detectors with receivers
  • Holographic gratings with pitches of the order of the wavelength of light, holographic optical elements and high density holographic storage
  • Higher order neural networks for time series prediction
  • Real time video image processing and pattern recognition
  • 3D display illumination using microlens arrays
  • LED colour separating backlights for illumination of liquid crystal displays
  • High sensitivity optical detection of coherent light in strong incoherent light background
  • Tuneable liquid crystal filled, Fabry-Perot, polarisation insensitive, narrow band, wavelength filters
  • Tuneable liquid crystal micro-prism image deflectors
  • Tuneable liquid crystal microlenses
