About this course

On completion of this course, you should be able to do the following:
Know and understand the scientific principles and methodology necessary to underpin your education in photonic subsystems, to enable appreciation of its scientific and engineering context, and to support your understanding of historical, current, and future developments and technologies
Comprehensively understand the scientific principles of photonic subsystems and related disciplines such as knowing how to generate terahertz and microwave radiation using lasers
Know and understand the mathematical principles necessary to underpin your education in photonic subsystems to enable you to apply mathematical methods, tools and notations proficiently in the analysis and solution of engineering problems
Be aware of developing technologies related to photonic subsystems such as generation of terahertz and microwave radiation using lasers
Ability to apply and integrate knowledge and understanding of other engineering disciplines such as telecommunications and metrology to support study of photonic subsystems
An ability to use fundamental knowledge to investigate new and emerging technologies such as how to fabricate planar photonic circuits and how to design photonic sub-systems for high precision measurement (metrology) of time and distance
Extract data pertinent to an unfamiliar problem, and apply in its solution computer-based engineering tools when appropriate

The department's short courses/CPD modules are aimed at those working in the telecommunications industry such as researchers, engineers, IT professionals and managers.
They're particularly suited to graduates in electronic and electrical engineering, communications engineering and computer science who want to further their knowledge on a particular topic, or work towards a Master's degree.
You don't need to have any pre-requisite qualifications to take this course.

The course takes place over four days, followed by a three-hour tutorial, and an optional exam.
A certificate of attendance will be issued on completion for those who take the module but not the exam.
If you take and pass the exam you'll get a certificate stating this, which includes your pass level.
