Description: Aims:
The aim of this unit is to develop students' understanding of the fundamental physics underlying both linear and nonlinear interactions of light with matter. A further aim is to describe how these interactions may be manipulated and enhanced by means of periodically patterned and microstructured optical waveguides.

Learning Outcomes:
After taking this unit the student should be able to:
* discuss the properties of waveguide modes as solutions to the scalar wave equation;
* describe in detail the properties of coupled waveguides, multicore fibres and waveguide transitions;
* explain the physical origins and implications of loss and dispersion in practical waveguides;
* describe the unique properties of photonic crystal fibres;
* give a detailed explanation of the basic properties of photonic bandgaps and defects in 2-D photonic crystals;
* demonstrate an understanding of the applications of the Lorentz oscillator model to describe nonlinear optical phenomena;
* demonstrate an understanding of the physical manifestations of the nonlinear refractive index on beam propagation;
* discuss the meaning and applications of the phase matching conditions in frequency conversion;
* discuss and mathematically describe nonlinear effects in optical fibres.

Skills:
Numeracy T/F A, Problem Solving T/F A.
