Microwave devices are fundamental to many modern electronics systems, including digital wireless communications. We have active research interests in developing and characterising microwave components and systems, with particular expertise in low phase-noise oscillators, filters and power efficient amplifiers.
Optical and optoelectronic semiconductor devices and subsystems permeate modern communications and information storage and are also increasingly important in medical, environmental, and industrial applications. As the device and system complexity increases, accurate theoretical models with predictive capability become more and more important, particularly after the burst of the telecoms bubble made costly trial and error design unattractive.
Here in York, we work on advancing theory, modelling and CAD of semiconductor optoelectronics in collaboration with several academic and industrial partners.
