Research
Nonlinear optical fibre; optical switching; optical bistability and instabilities; fibre gratings; mode-locking of fibre lasers; simulation of photonic systems. Engineering education research.
Application
Nonlinear properties of optical fib
re that provide a route to optical pulse generation and shaping; fibre structures such as gratings or rings that allow further control and manipulation of optical pulses; uses in optical communications or optical sensors. Engineering education research activities are focused on the use of new technology in teaching, project work, and design education.
