Course learning outcomes

On completion of this course, students should be able to:

  1. define and explain the propagation of light in conducting and non-conducting media;
  2. define and explain the physics governing laser behaviour and light matter interaction;
  3. apply wave optics and diffraction theory to a range of problems;
  4. apply the principles of atomic physics to materials used in optics and photonics;
  5. calculate the properties of various lasers and the propagation of laser beams;
  6. calculate properties of and design modern optical fibres and photonic crystals;
  7. use the tools, methodologies, language and conventions of physics to test and communicate ideas and explanations;
  8. integrate several components of the course in the context of a new situation (unique to postgraduate coursework).
