Single pump, parametric amplification in randomly-birefringent, unidirectionally spun fibers

Abstract
A systematic study of the effects of polarization mode dispersion on broad-band and narrow-band, single pump, fiber parametric amplifiers is realized through numerical solutions of the equations governing the interaction. The nonlinear polarization rotation is shown to be a relevant effect that can increase gain randomness when it mixes with polarization mode dispersion. In unidirectionally spun fibers the signal-pump alignment can be highly increased and the gain enhanced. However, in spite of the enhanced alignment, large polarization mode dispersion phase-mismatches the interaction and the gain decreases to zero.
