Optical fiber communication engineering is an educational application. If you are looking for optical fiber communication app so you are in a right place.

Polarization mode dispersion is the polarization dependence of the propagation characteristics of light waves in optical fibers. It can result from random birefringence and then needs to be described with statistical methods. In real single-mode optical fibers, imperfections cause the two possible polarizations to propagate at different phase velocities. This birefringence leads to different group velocities.

As the name suggests, the measure of dispersion shows the scatterings of … Dispersion engineering of mode-locked ﬁbre lasers R I Woodward MQ Photonics, Department of Engineering, Macquarie University, New South Wales, Australia E-mail: robert.woodward@mq.edu.au Received 7 November 2017, revised 22 December 2017 Accepted for publication 23 January 2018 Published 14 February 2018 Abstract Polarization mode dispersion is the polarization dependence of the propagation characteristics of light waves in optical fibers. It can result from random birefringence and then needs to be described with statistical methods. Single-mode dispersion data is obtained from measurements of the relative time-of-flight of light signals at various wavelengths. Light from an amplitude-modulated light-emitting diode (LED) is selected by a monochromator and launched into the fiber under test.

Polarization Mode Dispersion Defined PMD (Polarization Mode Dispersion) is the differential arrival time of the different polarization components of an input light pulse, transmitted by an optical fiber. This light pulse can always be decomposed into pairs of orthogonal polarization modes.
