Introduction to Chromatic Dispersion
Chromatic Dispersion (CD) is a broadening of the input signal as it travels
down the length of the fiber. Chromatic dispersion is closely related mathematically
to optical phase. It is the second derivative of optical phase with respect
to optical frequency, group delay being the first derivative.

Introduction to Jones Calculus
Jones Calculus is a mathematical technique for describing the polarization
state of light and calculating the evolution of the polarization state as light
passes through optical devices. Any state of polarization can be described
by a two-element Jones vector, and the linear operation of any optical device
can be fully described by a 2x2 Jones matrix. A system of multiple devices
can be straightforwardly modeled by multiplying the component Jones matrices
to yield a single system Jones matrix.

Introduction to Polarization
The interaction of polarized light with matter
can lead to a host of effects, some of which
are very useful for certain applications. However,
in many other
applications, polarization effects can degrade or limit the performance of
an optical system.

Introduction to Polarization Mode Dispersion
(PMD)
A fundamental property of single-mode optical
fiber and components, Polarization Mode Dispersion
(PMD) is a broadening of the input pulse
due to a phase delay
between input polarization states
