Description
This module explores how light may be controlled and guided, and how quantum physics may
be harnessed in the future to offer new and exciting opportunities in manipulating light.
This module will range over basic physics and topical applications. Topics include:
waveguides and optical fibre; lasers; amplifiers; nonlinear optics; polarization, optical
activity and birefringence, orbital angular momentum; entangled states; cavity QED; novel
light sources; photonic crystals, negative index materials.
Module Aims
This module aims to develop a detailed understanding of the physics that underpins
photonics and a familiarity with topics at the forefront of current optics research, such as
the production and manipulation of light in special states.
