Mauricio Yañez, "Pulse narrowing in optical fibers using polarization controls," Master's thesis, Dept. of Electrical and Computer Engineering, University of New Brunswick, (Fredericton, NB, Canada), May 2000.


A mathematical procedure aimed to compensate Polarization Mode Dispersion by reducing the root mean square pulsewidth of a signal through the optimization of the launching and receiving states of polarization has recently been proposed. It is the objective of this thesis to explore the nature of such compensation method. Analytically exact solutions are presented for the case in which the optical fiber consists of one, two and three segments of Highly-Birefringent (Hi-Bi) fiber. Numerical generated results are presented for a fiber consisting of an arbitrary number of segments of Hi-Bi fiber.

The solution of the mathematical procedure shows, in all cases, the existence of two sets of orthogonal input and output states of polarization which allow an output pulse to be narrower than the input pulse. The cost for obtaining a narrower pulse at the output of the fiber is a power loss.
