I have been a member of the EEE Department since 1985 as part of the Optoelectronics Research Group, now the Centre for Microsystems and Photonics. Prior to this, I worked on integrated optics research at Glasgow University for fibre optic communication systems. Since 1985, my research has involved areas such as fibre optic components, evanescent wave sensors, laser spectroscopy, photoacoustic spectroscopy and fibre laser systems.
I have taught several undergraduate courses including analogue and digital electronics and supervised many undergraduate projects in photonics. Over the years I have been closely involved with the management of the joint undergraduate course in electrical and mechanical engineering and currently I am deputy chair of the departmental courses and teaching committee.
My research is in the area of "photonics", which is the science and application of light, taking advantage of both the wave and photon nature of light for a wide variety of applications. Initially my research was focussed on photonics for optical communication systems and then later on optical sensors, particularly the use of lasers for absorption spectroscopy in detecting gases such as methane, carbon dioxide, etc. The high spectral density and tunability of near infra-red lasers make them ideal sources in spectroscopy and the use of fibre optics and components from the communications industry bring the added dimensions of flexibility and remote sensing.
Expertise & Capabilities
I have particular expertise in the following areas:
Fibre optic systems for absorption spectroscopy
DFB lasers for spectroscopy applications
Dynamics of fibre lasers for ring-down and intracavity spectroscopy
Evanescent field devices
Some of the areas where the research has led to industrial applications include:
Fibre optic methane sensors for monitoring of land-fill sites, mines and energy generation plants based on methane (OptoSci Ltd)
Gas monitoring and emissions control for fuel cells and gas turbine engines (Rolls Royce)
I have taught courses in analogue and digital electronics, optical waveguides, fibre optics, optical communication systems and photonics.
Academic / Professional qualifications
I graduated from Glasgow University with a Bachelor of Science (1st Class Honours Degree) in 1974 and then with a PhD degree in 1979 for research in integrated optics. I am currently a member of the Optical Society of America and the Institute of Physics.
