OPTO6008 Optical Fibre Technology I

Module Overview

Knowledge of basic principles of fibre optics will make up a significant part of the necessary skill base for students on the Optical Fibre Technologies MSc. In-depth knowledge of optical fibres as the light guiding medium is vital for understanding most other areas of optical fibre technology (telecommunications, sensors), and as support for the final project work. This module will describe four core areas – the key concepts of light propagation in optical fibre waveguides, various types of optical fibres and how they work, the key concepts of optical fibre fabrication and characterisation, together with the most common fibre components, thus making a foundational introduction for the rest of the modules in the MSc programme. This module is introductory, and its material is intended to introduce the field of fibre optics to relative newcomers. The skills and knowledge acquired during this course will form the foundation for much of the material taught in the Semester 2 courses, and for the final projects in Semester 3 of the MSc programme.

Aims and Objectives

Module Aims

The aim of the module is to provide an introduction to passive optical fibre technology. Fundamentals of propagation of light through optical fibres would be introduced first. The operating principles and key properties of a variety of optical fibres will be covered followed by technologies relating to fibre fabrication and fibre characterisation. Finally, fibre components and their conceptual operation will be introduced and two key application areas of optical fibre technology – telecommunications and optical sensors – will be briefly introduced.
