Description including Unit Aims

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

Intended Learning Outcomes

Having completed the unit, students will have an understanding of the operation of semiconductor diode lasers, PIN and avalanche detectors, amplifiers, modulators, and passive waveguides. Students will have a clear picture of how these components fit together in modern day optical communication systems, including optical communications, imaging and data storage.
