Description

Passive Components

This part of the unit describes in detail the key passive components in modern optical communication systems. It covers both fibre-based and photonic integrated circuit components. Electromagnetic analysis is used to gain an understanding of component operation

Optoelectronics and non-linear optics

This part of the module introduces the main techniques applicable to optoelectronic systems for the generation, detection, amplification and modulation of optical signals.

Elements:

Passive Components Dr M. J. Cryan

  • Electromagnetic analysis of optical fibres, slab, ridge, deep-etched waveguides, co- and contra-directional couplers
  • Filters, thin film devices, Fibre Bragg Gratings, planar waveguide devices
  • More complex components which are used in Wavelength Division Multiplexing (WDM) systems, such as AWGs and Optical Add-Drop Multiplexers
  • Future developments in these technologies will be reviewed and concepts such as Photonic Crystal-based devices will be introduced.

Active (optoelectronic) components Dr Krishna Balram

  • The basic SNR properties of linear avalanche diodes and noise equivalent power
  • Extension of avalanche diodes to Geiger mode photon counting
  • Applications of photon counting detectors (lifetime measurement, quantum cryptography)
  • CCD camera operation and performance
  • CMOS camera operation and performance
  • Free space optical communication systems
  • Non-linear optics
  • Three wave interactions, phase matching frequency doubling
  • Four wave mixing, intensity dependent refractive index and the all optical switch, solitons self focussing
  • Vertical cavity semiconductor lasers; principles of operation, advantages

Teaching details

Teaching will be delivered through a combination of synchronous and asynchronous sessions, including lectures, practical activities supported by drop-in sessions, problem sheets and self-directed exercises.

Assessment Details

All ILOs will be tested through an exam.

Resources

If this unit has a Resource List, you will normally find a link to it in the Blackboard area for the unit. Sometimes there will be a separate link for each weekly topic.

If you are unable to access a list through Blackboard, you can also find it via the Resource Lists homepage. Search for the list by the unit name or code (e.g. EENGM6000).
