This module covers the basic elements of electronic and optical physics that will enable module participants to understand the operational principles of modern semiconductor-based electronic and photonic (optoelectronic) devices and systems.
The theory of semiconductors and advanced aspects of microelectronic device technology be will presented, including the characteristics of microelectronic devices such as diodes and transistors under DC and AC excitation. The structure and properties of BJT and MOS circuitry such as inverters and memory components will also be studied.
Students will be introduced to the nanophotonics in the context of integrated photonics and silicon photonic chip technology together with their application to optical telecommunications. They will also learn the principles of light propagation (ray optics and wave optics) photonic waveguide devices such as modulators, optical properties of materials, photonic detectors and light generation, including light emitting diodes and lasers.
The module lectures will be augmented with laboratory sessions, in-class practical demonstrations and tutorials.

Equivalent to the range 60%-69%. Is able to analyse a task or problem to decide which aspects of theory and knowledge to apply. Solutions are of a workable quality, demonstrating understanding of underlying principles. Major themes can be linked appropriately but may not be able to extend this to individual aspects. Outputs are readily understood, with an appropriate structure but may lack sophistication.
Equivalent to 40%. Uses key areas of theory or knowledge to meet the Learning Outcomes of the module. Is able to formulate an appropriate solution to accurately solve tasks and questions. Can identify individual aspects, but lacks an awareness of links between them and the wider contexts. Outputs can be understood, but lack structure and/or coherence.
Equivalent to the range 70%+. Assemble critically evaluated, relevent areas of knowledge and theory to constuct professional-level solutions to tasks and questions presented. Is able to cross-link themes and aspects to draw considered conclusions. Presents outputs in a cohesive, accurate, and efficient manner.
