“…PMD leads to the pulse broadening caused by varying group velocities for the pulses with different states of polarization (SOPs) [1,2] whereas PDG leads to an uncontrollable output gain variation caused by its dependence on the input signal SOP [3][4][5][6][7]. By the traditional approach, spinning the fiber periodically, it is possible to reduce PMD to below 0.04 ps/km 1/2 [8,9], but this is accompanied with a simultaneous increase in Raman PDG [3][4][5][6][7]. Sergeyev et al have shown that it is possible to mitigate both PDG and PMD simultaneously by using a two-section fiber ('two-section approach') in which the first section has no spin and the second one is periodically spun [5][6][7].…”

Abstract:We report on a theoretical study of activated polarization pulling and de-correlation of signal and pump states of polarization based on an advanced vector model of a fiber Raman amplifier accounting for random birefringence and two-scale fiber spinning. As a result, we have found that it is possible to provide de-correlation and simultaneously suppress PDG and PMD to 1.2 dB and 0.035 ps/km 1/2 respectively. ©2011 Optical Society of America References and links1.

“…The free parameters in the model include: 1) glass viscosity (determined by the glass properties and the furnace temperature profile); 2) surface tension; 3) the length of the drawing furnace; 4) the initial preform geometry (i.e., inner and outer diameters); and 5) the feeding and drawing speeds. (4) and the boundary conditions are given by (5) where all notation is defined in Table I. Subscripts denote differentiation.…”

Abstract-A method for modeling the fabrication of capillary tubes is developed that includes the effects of preform rotation, and is used to reduce or remove polarization mode dispersion and fiber birefringence. The model is solved numerically, making use of extensive experimental investigations into furnace temperature profiles and silica glass viscosities, without the use of fitting parameters. Accurate predictions of the geometry of spun capillary tubes are made and compared directly with experimental results, showing remarkable agreement and demonstrating that the mathematical modeling of fiber drawing promises to be an accurate predictive tool for experimenters. Finally, a discussion of how this model impacts on the rotation of more general microstructured optical fiber preforms is given.Index Terms-Mathematical modeling, optical fiber, optical fiber applications, optical fiber fabrication, optical fiber theory.

“…Conventional (solid) preforms are routinely rotated to introduce a twist into the final fibre, since this reduces polarization mode dispersion (PMD) [4,5,6]. It is not obvious that the same process may be applied to holey-fibre preforms without producing adverse macroscopic geometry-changes that severely compromise the microstructure within.…”

Abstract:We construct a fluid mechanics model of the drawing of microstructured optical fibres ('holey fibres'). This model can be used to understand and quantify methods for controlling the fibre geometry. The effects of preform rotation are included to examine methods for reducing fibre birefringence. Asymptotic numerical-solutions are obtained and applied to two typical microstructured-fibres and a number of practical suggestions are made for achieving sub-mm spin pitches without damaging the microstructure within.
