Personal profile

Research interests


Dr Allsopp received the degrees of BSc in Physics, MSc and PhD in Electronic Engineering from the University of Sheffield in 1971, 1974 and 1977. From 1977 to 1979 he was at Ferranti Electronics Limited developing high speed Si transistors and integrated circuits.

From 1979 to 1984 he was at UMIST researching defects in semiconductors, and from 1984 to 1986 he was at British Telecom Research Laboratories, Martlesham Heath.

In 1986 he joined the University of York where he established a group researching photonic devices. In 1999 he joined the Optoelectronics Group at the University of Bath.

For 2006-2007 he was Royal Academy of Engineering/ Leverhulme Trust Senior Research Fellow researching nanofabrication technologies for photonic applications. 


  • GaN Light Emitting Diodes for solid state lighting
    This collaborative research project funded by the DTI involves advancing LED performance. The research exploits the University’s capability to grow state-of-the-art Group III-Nitride epitaxy by MOVPE and HVPE, its facilities nanofabrication and advanced optoelectronic device characterisation.
  • Novel nanofabrication techniques and their application to sub-wavelength optical devices and to advanced Group III-Nitride epitaxial growth (funded by the European Union FP 6 STREP “N2T2”)  
  • Advanced optical modulators and switches based quantum well effects(EPSRC funded).
    This research has two strands: an investigation of the application of electroabsorption modulators to the generation and detection of TeraHertz radiation and of the feasibility of using intersubband absorption to high speed optical modulation.
  • Sensors and electronics for harsh environments (EU funded via FP7)
    This project will exploit the properties of c-plane GaN for sensing pressure, mechanical force and temperature in harsh environments, including high temperatures (above 500°C). The research includes developing GaN epitaxial growth on Si/polycrystalline diamond composite substrates designed for heat extraction and/or thermal stability. Other sensor research includes developing wide area arrays of sensors for robotic skin (supported by OCRobotics, Bristol).

Lowering the cost of LED lighting

Duncan Allsopp discusses his involvement in a consortium looking at solving problems that limit take-up of LED lights. Read more
