Level: Level 4
Target Students: MEng, MRes, MSc and PhD students of Electrical and Electronic Engineering.
|Autumn ||Assessed by end of Autumn Semester |
and one of: HG1M11, HG1M12, HG2ME1/2, or equivalent
Summary of Content: This module introduces the principles and application of a wide range of photonic devices, currently used in photonics telecoms. The specific topics covered include:
- carrier transport and recombination processes in semiconductors;
- light-emitting diodes (LEDs);
- laser diodes (both for signal sources and amplifier pumps);
- LED and laser diode modulation (rate equation descriptions, equivalent circuits, modulation and small-signal performance analysis);
- APD and PIN diode detectors;
- detector response (sensitivity, bandwidth and noise);
- signal propagation effects, including attenuation, phase and group velocity, chromatic dispersion, modulation-induced chirp, pulse width broadening and compression.

Education Aims: To introduce the underlying physics and mathematics required for the analysis and design of photonic communications devices. To consider the impact of the device performance in practical data transmission links, including signal modulation, propagation effects and noise.
By the end of the module, students should be able to:
- demonstrate a good understanding of the operating principles and underlying physical processes used in active semiconductor photonic devices;
- relate the performance limitations of active semiconductor photonic devices to both the device design and the underlying physical processes and materials properties;
- demonstrate an appreciation of how the application requirements influence the design of active semiconductor photonic devices;
- demonstrate an ability to use physical analysis, based on logic and/or mathematics, to understand and describe the behaviour and performance of active semiconductor photonic devices.
