Description The purpose of this module is to introduce new PhD students working in the general optical communications field to all the components that are employed in building a photonics system. The module will introduce the operation of optical sources, detectors, amplifiers, modulators, and filters that are used in optical communications systems. | |||||||||||||||||||||||||||||||||||||
Learning Outcomes 1. Understand the underlying physics of the components that make an optical system and their roles and limitations 2. Describe the characteristics and performance of optical fibres and their impact on the overall system performance 3. Outline and be able to use the techniques and the technologies that make possible the modulation and demodulation processes in optical systems in order to achieve a required performance 4. Understand the nature of, and be able to use the performance metrics employed in system design, namely BER and S/N ratio 5. Analyse the limitations on system performance imposed by the nonlinear optical behaviour of fibres and be able to use the techniques for the mitigation of these effects 6. Describe the limitations of TDM systems in terms of components and performance, and the advantages of WDM systems and their limitations 7. Outline the concepts of fibre optic networks for TDM and WDM networks and the merits of an all optical fibre network 8. Simulate basic optical systems using design software | |||||||||||||||||||||||||||||||||||||
