Resistance Of Solitons To The Effects Of Polarization Dispersion In Optical Fibers.

Using numerical simulation, we show that solitons of any pulsewidth can avoid splitting or excessive broadening in response to birefringence of randomly varying orientation, as long as the fiber's polarization dispersion parameter, in ps/km sup (1/2), is less than 0.3D sup (1/2), where D is the dispersion parameter in ps/nm/km. Nevertheless, we also find that polarization dispersion tends to produce a significant amount of dispersive wave radiation from the soliton.
