Abstract--In this letter, we present a novel polarization diver-
sity receiver for mitigating polarization-mode dispersion (PMD).
We show that with simple fixed optics and electronics we can
significantly decrease the outage probability due to PMD and
can achieve better performance than an electronic equalization
solution using no diversity. By incorporating equalization into
the diversity receiver structure, further performance improve-
ments can be achieved and the intersymbol interference due to
higher order PMD distortions can be reduced. We demonstrate
the performance advantages of the proposed diversity receiver
using importance sampling to accurately calculate the outage
probability due to PMD.
Index Terms--Diversity methods, equalizers, intersymbol inter-
ference, optical communications, optical fiber polarization, PMD
