Jones Calculus and Liquid Crystals
We introduce Jones calculus to keep track of polarization direction and use it to describe a number of examples including polarization rotation in a twisted nematic liquid crystal.

Nonlinear optics 1
We introduce non-linear optics and discuss various forms of 3 wave mixing including frequency converters, optical parametric amplifiers (OPAs), optical parametric oscillators (OPOs) and second harmonic generation (SHG)

Faraday Rotators in LIGO
We look at how aspects of this class relate to the Laser Interferometer Gravitational Wave Observatory (LIGO) and investigate the design of the LIGO Faraday Isolators
12 Feb 2009
We provide a physical description for the origin of optical activity and faraday rotation in a material and useeigenmodes as well as coupled mode analysis to solve for the behavior of fields propagating through an optically active material.

Propagation in Anisotropic Materials
We look at solutions to the wave equation in anisotropic materials and the "normal shells" that describe of those solutions.
