This module introduces the main components of modern day optoelectronic systems. This will include active devices for the generation, detection, amplification and modulation of optical signals and the key passive components in modern optical communication systems.
Elements
Optoelectronic Devices- Passive Components Dr M.J. Cryan
Waveguides: Introduction to passive waveguides and their modes. Explain the single mode optical fibre, losses and dispersion. Directional couplers, Bragg reflectors and filters.
Active Components Prof J.G. Rarity and Dr M. Thompson
Sources: introduction to electron-photon interactions in semiconductors. Explain the operation of the light emitting diode (LED). Explain the conditions required for laser action and distinguish the characteristics of laser emission from LED emission. Describe the current/voltage, power/current and frequency characteristics of light-emitting and laser diodes. Describe the Fabry-Perot and distributed-feedback and distributed-Bragg-reflector laser diodes, and explain the factors that determine their line-widths.
Detectors: explain the principles of optical detectors including PIN photodiodes and avalanche detectors. Discuss the ideal, quantum-noise limited receiver obeying Poisson statistics and relate number of detected photons to bit-error-ratio. Explain why the sensitivity of the best receivers falls short of the ideal.
Amplifiers and modulators: Introduce the optical amplifiers and optical modulators. Give examples of fibre amplifiers and semiconductor laser amplifiers. Introduce electro-optic and electro-absorption modulators. Indicate their different applications in optical fibre communication systems.
Systems: explain how the elements introduced above fit into a modern day optical communications system.
Project Phase
The project contains a research or investigative element which allows you to demonstrate individual talent and intellectual ability. It attempts to mirror a research and/or development project of the type you might encounter upon graduation and as such contains elements of project planning and budgetary control. The project report also provides an opportunity for you to demonstrate report structuring and writing skills.
