One of the major impairments in high-speed optical transmission links is Polarization-Mode Dispersion (PMD).
We propose the method of electronic predistortion (EPD) for the mitigation of PMD. This approach has already
been successfully applied for the compensation of Chromatic Dispersion (CD) and Fiber-Nonlinearities. The
advantage of this method is that impairments can efficiently be mitigated without the need for coherent reception.
The proposed scheme is based on the possibility to control the optical field at the transmitter by using two complex
modulators for the modulation of two orthogonally polarized optical signals.
If the physical origin of PMD is exactly known then the ideal predistorted field and the corresponding electrical
driving signals can be computed accurately. In practice, however, this information is not available. Therefore it
is shown how to determine appropriate driving signals for a set of measured PMD parameters.
Measurements will be communicated through a feedback channel in practice. We suggest a possible strategy
for application of this technique in scenarios, in which the adaptation speed is intrinsically limited due to the
Numerical simulations reveal that the use of EPD can significantly increase the tolerance towards PMD in
comparison to a system without compensation.
